Correct Answer: A

Rationale: Correct Answer: A (Iron, folic acid, and B12) Rationale: 1. Iron: Renal failure patients often have anemia due to decreased erythropoietin production. 2. Folic acid and B12: Important for red blood cell production and maturation. 3. Corrects underlying causes of anemia in renal failure patients. Summary: B: Increasing protein doesn't directly address anemia in renal failure. C: Vitamin D and calcium are not primary treatments for anemia in renal failure. D: Calcium and folic acid alone do not address the specific deficiencies seen in renal failure anemia.

Correct Answer: C

Rationale: The correct answer is C: Mental. Nursing assessments typically include physical, focused, and emergency assessments. Mental assessments are more commonly associated with psychiatric nursing rather than general nursing assessments. Mental assessments focus on assessing a patient's mental status, emotions, and cognitive functions, which are not typically part of routine nursing assessments. Therefore, mental assessments do not fall under the types of assessments typically performed by general nurses.

Correct Answer: B

Rationale: The correct answer is B: ondansetron (Zofran). Ondansetron is a selective serotonin receptor antagonist that effectively targets the serotonin receptors in the chemoreceptor trigger zone to relieve nausea and vomiting. It is commonly used in chemotherapy-induced nausea and vomiting. A: Metoclopramide is a dopamine receptor antagonist and primarily used for gastrointestinal motility disorders, not specifically for nausea relief. C: Hydroxyzine is an antihistamine with sedative properties, primarily used for anxiety and itching, not specifically for nausea relief. D: Prochlorperazine is a dopamine receptor antagonist primarily used for treating psychotic disorders, not specifically for nausea relief. In summary, ondansetron is the correct choice as it targets serotonin receptors specifically for relieving nausea and vomiting, whereas the other options focus on different mechanisms of action.

Correct Answer: C

Rationale: The correct answer is C because using the inhaler every time the patient feels short of breath, even without a flare-up, is not the recommended practice for managing COPD. Inhalers should be used as prescribed by the healthcare provider or only during exacerbations. Here's the rationale: 1. Using the inhaler excessively can lead to overuse of medication and potential side effects. 2. It is important for patients to differentiate between regular management and acute exacerbations. 3. Monitoring oxygen levels (choice D) is essential for COPD management. 4. Quitting smoking (choice A) and deep breathing exercises (choice B) are positive self-management strategies for COPD.
