A client with several chronic health problems has been newly diagnosed with a qualitative platelet defect. What component of the patient's previous medication regimen may have contributed to the development of this disorder?
- A. Calcium carbonate
- B. Vitamin B12
- C. Aspirin
- D. Vitamin D
Correct Answer: C
Rationale: Aspirin may induce a platelet disorder. Even small amounts of aspirin reduce normal platelet aggregation, and the prolonged bleeding time lasts for several days after aspirin ingestion. Calcium, vitamin D, and vitamin B12 do not have the potential to induce a platelet defect.

A patient's absolute neutrophil count (ANC) is 440/mm3. But the nurse's assessment reveals no apparent signs or symptoms of infection. What action should the nurse prioritize when providing care for this patient?
- A. Meticulous hand hygiene
- B. Timely administration of antibiotics
- C. Provision of a nutrient-dense diet
- D. Maintaining a sterile care environment
Correct Answer: A
Rationale: Providing care for a patient with neutropenia requires that the nurse adhere closely to standard precautions and infection control procedures. Hand hygiene is central to such efforts. Prophylactic antibiotics are rarely used and it is not possible to provide a sterile environment for care. Nutrition is highly beneficial, but hand hygiene is the central aspect of care.
A nurse is caring for a patient who has sickle cell anemia and the nurses assessment reveals the possibility of substance abuse. What is the nurses most appropriate action?
- A. Encourage the patient to rely on complementary and alternative therapies.
- B. Encourage the patient to seek care from a single provider for pain relief.
- C. Teach the patient to accept chronic pain as an inevitable aspect of the disease.
- D. Limit the reporting of emergency department visits to the primary health care provider.
Correct Answer: B
Rationale: The patient should be encouraged to use a single primary health care provider to address health care concerns. Emergency department visits should be reported to the primary health care provider to achieve optimal management of the disease. It would be inappropriate to teach the patient to simply accept his or her pain. Complementary therapies are usually insufficient to fully address pain in sickle cell disease.
A patient, 25 years of age, comes to the emergency department complaining of excessive bleeding from a cut sustained when cleaning a knife. Blood work shows a prolonged PT but a vitamin K deficiency is ruled out. When assessing the patient, areas of ecchymosis are noted on other areas of the body. Which of the following is the most plausible cause of the patients signs and symptoms?
- A. Lymphoma
- B. Leukemia
- C. Hemophilia
- D. Hepatic dysfunction
Correct Answer: D
Rationale: Prolongation of the PT, unless it is caused by vitamin K deficiency, may indicate severe hepatic dysfunction. The majority of hemophiliacs are diagnosed as children. The scenario does not describe signs or symptoms of lymphoma or leukemia.
The results of a patient's most recent blood work and physical assessment are suggestive of immune thrombocytopenic purpura (ITP). This patient should undergo testing for which of the following potential causes?
- A. Hepatitis
- B. Acute renal failure
- C. HIV
- D. Malignant melanoma
- E. Cholecystitis
Correct Answer: A,C
Rationale: Viral illnesses have the potential to cause ITP. Renal failure, malignancies, and gall bladder inflammation are not typical causes of ITP.
A woman who is in her third trimester of pregnancy has been experiencing an exacerbation of iron deficiency anemia in recent weeks. When providing the patient with nutritional guidelines and meal suggestions, what foods would be most likely to increase the woman's iron stores?
- A. Salmon accompanied by whole milk
- B. Mixed vegetables and brown rice
- C. Beef liver accompanied by orange juice
- D. Yogurt, almonds, and whole grain oats
Correct Answer: C
Rationale: Food sources high in iron include organ meats, other meats, beans (e.g., black, pinto, and garbanzo), leafy green vegetables, raisins, and molasses. Taking iron-rich foods with a source of vitamin C (e.g., orange juice) enhances the absorption of iron. All of the listed foods are nutritious, but liver and orange juice are most likely to be of benefit.
