D454 Adult Health III - Set 3 - Part 1

Correct Answer: Patient one needs iron supplementation to normalize the red blood cells, while Patient two needs vigorous exercise to stimulate the bone marrow into producing more cells

Option d is correct because difficulty arousing a thrombocytopenic patient may signal intracranial hemorrhage, which is the most life-threatening complication and requires immediate emergency intervention from the medical provider. Option a is incorrect because small bruises on the forearms are a common and expected finding in thrombocytopenia and do not indicate an immediately life-threatening emergency requiring urgent notification. Option b is incorrect because bleeding gums after brushing, while concerning and worth documenting, represent a minor mucosal bleed rather than a critical emergency requiring immediate provider contact. Option c is incorrect because petechiae are a typical clinical manifestation of low platelet counts and indicate capillary bleeding, not a dangerous internal hemorrhage requiring emergency intervention.

Correct Answer: Consult the provider about this specific order

Option a is correct because in ITP the immune system actively destroys platelets, so transfused platelets will also be rapidly destroyed. Transfusions are typically reserved for life-threatening bleeding or counts below ten. Option b is incorrect because blindly administering platelets in ITP without questioning the order ignores the disease mechanism where autoimmune antibodies will rapidly destroy the transfused platelets as well. Option c is incorrect because rechecking the platelet count does not address the fundamental concern that platelet transfusions are generally ineffective in ITP due to ongoing autoimmune platelet destruction. Option d is incorrect because while corticosteroids may be part of ITP treatment, administering them before a transfusion does not resolve the core issue of questioning the appropriateness of the transfusion itself.

Correct Answer: Shave only with an electric razor at home

Option c is correct because electric razors significantly reduce the risk of skin cuts compared to manual razors. Bleeding prevention is a priority nursing intervention for patients with low platelet counts. Option a is incorrect because firm-bristled toothbrushes can traumatize gum tissue and cause bleeding. Patients with thrombocytopenia should be instructed to use only soft-bristled toothbrushes at home. Option b is incorrect because dental floss is contraindicated when platelet counts are low. Flossing can damage delicate gum tissue and trigger bleeding that is difficult to control in thrombocytopenic patients. Option d is incorrect because applying cold packs before injections is not a standard bleeding prevention strategy for thrombocytopenia. The priority is to avoid intramuscular injections entirely when platelet counts are low.

Correct Answer: Check all stools for occult blood regularly

Option b is correct because checking stools for occult blood helps detect gastrointestinal bleeding early, which is a significant risk for patients with thrombocytopenia and allows timely intervention before major hemorrhage. Option a is incorrect because aspirin inhibits platelet function and would further impair the already compromised clotting ability of a thrombocytopenic patient, significantly increasing their risk of dangerous bleeding episodes. Option c is incorrect because vigorous physical activity increases the risk of injury and subsequent bleeding in a patient whose platelet count is already dangerously low and unable to form adequate clots. Option d is incorrect because intramuscular injections are contraindicated in thrombocytopenia due to the risk of uncontrolled bleeding into muscle tissue. Alternative routes of medication administration should be used.

Correct Answer: Your immune system produces antibodies that mistakenly attack and destroy your own platelets as foreign invaders

Option a is correct because ITP is an autoimmune condition where the body produces antibodies that incorrectly identify platelets as foreign, leading to their accelerated destruction by the immune system. Option b is incorrect because ITP does not involve bone marrow failure or permanent marrow damage. The bone marrow typically functions normally but cannot keep pace with the rapid immune-mediated platelet destruction. Option c is incorrect because while viral infections can sometimes trigger ITP, the destruction mechanism is autoimmune antibodies attacking platelets, not a virus directly destroying the platelets in circulation. Option d is incorrect because ITP is an autoimmune disorder, not a drug-induced condition. While some medications can cause thrombocytopenia, that represents a different diagnosis entirely from immune thrombocytopenic purpura.

Correct Answer: Immobilize the affected joint without any delay

Option c is correct because immobilizing the joint during active bleeding into the joint space prevents further damage and hemorrhage. Movement and manipulation during hemarthrosis worsen bleeding and joint destruction significantly. Option a is incorrect because heat application is contraindicated during active joint bleeding in hemophilia. Warmth causes vasodilation, which increases blood flow to the area and worsens the hemorrhage into the joint. Option b is incorrect because active range of motion exercises are contraindicated during an acute hemarthrosis episode. Movement increases bleeding into the joint space and causes additional tissue and cartilage damage. Option d is incorrect because while pain management is important, the immediate priority is stopping further bleeding by immobilizing the joint. Assessment and stabilization of the bleeding come before comfort measures alone.

Correct Answer: Dark tarry stools noted during assisted toileting

Option d is correct because dark tarry stools, called melena, indicate active gastrointestinal hemorrhage. This is the most serious complication requiring immediate provider notification in a hemophilia patient after a fall. Option a is incorrect because while a large bruise is consistent with hemophilia and should be documented, it represents external soft tissue bleeding rather than the immediately life-threatening internal hemorrhage that melena suggests. Option b is incorrect because mild joint swelling, while characteristic of hemarthrosis in hemophilia, does not carry the same immediate life-threatening urgency as active gastrointestinal bleeding indicated by tarry stools. Option c is incorrect because generalized body aches are a common and relatively nonspecific complaint that does not indicate a dangerous acute hemorrhage requiring immediate emergency intervention from the medical provider.

Correct Answer: Von Willebrand disease impairs normal platelet adhesion function

Option b is correct because von Willebrand factor is specifically needed for normal platelet adhesion to damaged blood vessel walls. The disease affects both platelet adhesion and clotting factor function simultaneously. Option a is incorrect because hemophilia involves deficiency of specific clotting factors such as Factor VIII, not a primary problem with platelet adhesion. Platelet adhesion disruption is characteristic of von Willebrand disease instead. Option c is incorrect because although both are bleeding disorders, they affect different aspects of hemostasis. Hemophilia involves clotting factor deficiency while von Willebrand disease affects both platelet adhesion and clotting factors. Option d is incorrect because von Willebrand disease does not only affect clotting factors. It also impairs platelet adhesion to damaged endothelium, which is actually the distinguishing characteristic of this particular bleeding disorder.

Correct Answer: Bleeding time measurement results for the patient

Option a is correct because bleeding time is the key laboratory test for monitoring von Willebrand disease. Von Willebrand factor is required for normal platelet adhesion to damaged endothelium and prolonged bleeding time reflects this. Option b is incorrect because white blood cell count evaluates immune function and infection risk, not bleeding or clotting ability. It is not the priority laboratory test for monitoring von Willebrand disease specifically. Option c is incorrect because serum potassium and electrolyte levels assess metabolic and cardiac function, not hemostasis or bleeding risk. These labs are not directly relevant to von Willebrand disease monitoring. Option d is incorrect because fasting blood glucose and metabolic panels evaluate endocrine and metabolic function. They do not provide information about the bleeding and clotting dysfunction present in von Willebrand disease.

Correct Answer: This is an inherited disorder passed through family genetics

Option c is correct because von Willebrand disease is the most common inherited bleeding disorder. It is a hereditary condition passed genetically through families, affecting both platelet adhesion and clotting factor function. Option a is incorrect because von Willebrand disease is not caused by infections. It is a genetic hereditary condition present from birth, and repeated infections play no role in causing this particular bleeding disorder. Option b is incorrect because environmental toxins do not cause von Willebrand disease. The condition is inherited genetically and is present from birth regardless of environmental exposures or toxic substance contact throughout life. Option d is incorrect because nutritional deficiency does not cause von Willebrand disease. While poor nutrition can affect overall health, this specific bleeding disorder is genetic and inherited, not caused by dietary factors.

Correct Answer: Flush all intravenous lines with normal saline only

Option d is correct because all forms of heparin exposure must be eliminated in HIT, including heparin flushes and heparin-coated devices. Intravenous lines must be flushed exclusively with normal saline to prevent further exposure. Option a is incorrect because low molecular weight heparin is still a form of heparin and must also be stopped immediately in HIT. Switching to LMWH would continue the dangerous immune-mediated reaction against platelet complexes. Option b is incorrect because increasing the heparin rate would worsen the immune-mediated reaction causing HIT. All heparin must be stopped immediately, not increased, to prevent life-threatening thrombotic and bleeding complications. Option c is incorrect because heparin-coated intravenous devices must be removed and replaced in HIT. Any ongoing heparin exposure, even from coated tubing, can perpetuate the dangerous immune-mediated platelet destruction process.

Correct Answer: Activated partial thromboplastin time results

Option b is correct because the activated partial thromboplastin time is the primary laboratory test monitored to detect heparin-induced thrombocytopenia. Changes in this value along with falling platelet counts signal possible HIT development. Option a is incorrect because prothrombin time and INR are primarily used to monitor warfarin therapy effectiveness, not heparin therapy. These values are not the primary screening tool for detecting heparin-induced thrombocytopenia. Option c is incorrect because the complete metabolic panel evaluates kidney function, electrolytes, and glucose levels. It does not provide specific information about heparin's effects on coagulation or platelet destruction in HIT. Option d is incorrect because serum albumin and protein levels assess nutritional status and liver function. These values have no direct role in monitoring for heparin-induced thrombocytopenia or its associated coagulation changes.

Correct Answer: A seventy-eight-year-old patient admitted with septicemia

Option a is correct because septicemia is one of the most significant triggers for disseminated intravascular coagulation. Advanced age combined with systemic infection places this patient at the highest risk for DIC. Option b is incorrect because an isolated wrist fracture in an otherwise healthy forty-year-old does not represent the type of massive trauma or systemic illness that typically triggers disseminated intravascular coagulation development. Option c is incorrect because mild dehydration in a thirty-year-old is a common and easily treatable condition that does not involve the systemic inflammatory response or tissue destruction that triggers DIC development. Option d is incorrect because well-controlled hypertension managed with medication does not create the systemic clotting cascade activation or widespread tissue damage that serves as a trigger for disseminated intravascular coagulation.

Correct Answer: Disseminated intravascular coagulation is likely developing

Option c is correct because oozing blood simultaneously from incision sites, IV sites, and puncture sites is the earliest clinical manifestation of DIC. The combination of sepsis and multisite bleeding strongly suggests this diagnosis. Option a is incorrect because while vitamin K deficiency can impair clotting, it typically does not present with the acute simultaneous oozing from multiple sites in the setting of sepsis that characterizes early DIC onset. Option b is incorrect because normal postoperative bleeding is localized to the surgical site and resolves with standard interventions. Simultaneous bleeding from multiple unrelated sites in a septic patient is not a normal finding. Option d is incorrect because pain medications do not typically cause the pattern of simultaneous multifocal oozing from incisions and IV sites. This presentation with concurrent sepsis points specifically toward DIC development.

Correct Answer: Elevated D-dimer levels combined with decreased fibrinogen levels

Option d is correct because DIC laboratory findings characteristically show elevated D-dimer from widespread fibrin breakdown, decreased fibrinogen from consumption, prolonged clotting times, and decreased platelet counts simultaneously. Option a is incorrect because DIC causes platelet consumption leading to decreased platelet counts, not increased counts. D-dimer levels would be elevated from ongoing fibrinolysis and clot breakdown, not decreased as stated. Option b is incorrect because DIC causes prolonged clotting times as clotting factors are consumed by the pathological clotting process. Fibrinogen levels decrease rather than remain normal due to this same consumption process. Option c is incorrect because fibrin split products are characteristically elevated in DIC as widespread clots are broken down by the fibrinolytic system. Platelet counts decrease rather than remain normal due to consumption.

Correct Answer: Disconnect the transfusion and infuse normal saline

Option a is correct because back pain and dyspnea within minutes of starting a transfusion indicate an acute hemolytic reaction. The transfusion must be disconnected immediately and normal saline infused through new tubing. Option b is incorrect because slowing the rate of an acute hemolytic transfusion reaction is dangerous and inadequate. The incompatible blood must be completely stopped, not merely slowed, to prevent potentially fatal hemolysis from continuing. Option c is incorrect because acetaminophen is appropriate for febrile non-hemolytic reactions, not acute hemolytic reactions. Back pain with dyspnea occurring within minutes indicates a far more dangerous reaction requiring immediate transfusion discontinuation. Option d is incorrect because simply documenting findings and monitoring delays critical intervention during an acute hemolytic reaction. This is a medical emergency requiring immediate action, not continued passive observation and documentation.

Correct Answer: Febrile non-hemolytic transfusion reaction occurring

Option b is correct because chills, mild fever, and headache appearing thirty or more minutes after starting the transfusion are the classic presentation of a febrile non-hemolytic reaction, the most common transfusion reaction type. Option a is incorrect because acute hemolytic reactions present with back pain, dyspnea, and tachycardia typically within the first fifteen minutes of the transfusion. The timing and milder symptom pattern described do not match this reaction. Option c is incorrect because transfusion-related acute lung injury presents with acute respiratory distress, bilateral pulmonary infiltrates, and significant hypoxia. Chills and a mild headache are not characteristic features of TRALI presentation. Option d is incorrect because severe allergic or anaphylactic reactions present with urticaria, itching, bronchospasm, and potential cardiovascular collapse. Chills with a mild fever and headache describe a much milder and different reaction type.

Correct Answer: Monitor temperature readings every four hours consistently

Option d is correct because fever may be the only sign of infection in a neutropenic patient. Checking temperature every four hours is the priority nursing intervention for early detection of potentially fatal infections. Option a is incorrect because fresh flowers are contraindicated in neutropenic patient rooms. Flowers and standing water harbor bacteria and fungi that can cause life-threatening opportunistic infections in severely immunocompromised patients. Option b is incorrect because visitors with any active infections, including common colds, pose a serious infection risk to neutropenic patients. The nurse should restrict visits from anyone showing signs of illness. Option c is incorrect because fresh unpeeled fruits can harbor bacteria on their surfaces and are generally restricted in neutropenic diets. Only thoroughly washed and peeled or cooked foods are considered safe for these patients.

Correct Answer: Within one hour of the fever being detected

Option c is correct because febrile neutropenia is a medical emergency requiring antibiotic therapy initiation within one hour of fever onset. Treatment often begins before culture results return because delays can prove fatal. Option a is incorrect because waiting six hours to initiate antibiotics in a febrile neutropenic patient is far too long. Each hour of delay significantly increases the risk of sepsis progression and mortality in this vulnerable population. Option b is incorrect because waiting for blood culture results before starting antibiotics in febrile neutropenia is dangerous. Cultures may take days to return, and the patient requires empiric antibiotic coverage immediately upon fever detection. Option d is incorrect because delaying antibiotic initiation until the next shift is a potentially fatal error in febrile neutropenia. This is a medical emergency where prompt treatment within one hour directly impacts patient survival.

Correct Answer: Avoid all crowds and report any fever immediately

Option a is correct because avoiding crowds reduces infection exposure and immediately reporting fever enables rapid treatment. These are the most critical self-care behaviors for a neutropenic patient recovering at home. Option b is incorrect because resuming all normal activities immediately could expose the recovering neutropenic patient to infection sources in public settings before their immune system has adequately recovered from chemotherapy effects. Option c is incorrect because fresh flowers harbor bacteria and fungi in the soil and standing water. They are specifically contraindicated in the homes of neutropenic patients due to the serious risk of opportunistic infection. Option d is incorrect because discontinuing prescribed medications without provider guidance is dangerous for any patient, especially one recovering from chemotherapy-induced neutropenia who may need continued supportive medications for safe recovery.
