1. A patient has acute respiratory failure (ARF). Which of the following would the nurse expect to find?

Correct answer: B

Rationale: In acute respiratory failure, hypoxemia (low blood oxygen) and hypercapnia (high blood carbon dioxide) are commonly observed. Choice A is incorrect because alkalosis (high pH) and hyperventilation are not typically seen in acute respiratory failure. Choice C is incorrect as it mentions alkalosis and high potassium, which are not characteristic of acute respiratory failure. Choice D is also incorrect because elevated sodium and acidosis are not typically associated with acute respiratory failure.

2. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What important instruction should the nurse provide about the use of this medication?

Correct answer: C

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels. This is crucial for the effectiveness of medroxyprogesterone acetate in treating endometriosis. Choice A is incorrect because there is no specific instruction related to food intake. Choice B is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful. Choice D is unrelated to the administration of medroxyprogesterone acetate and is not a specific consideration for this medication.

3. A patient has been diagnosed with chronic renal failure. Which of the following agents will assist in raising the patient's hemoglobin levels?

Correct answer: A

Rationale: The correct answer is A: Epoetin alfa (Epogen, Procrit). Epoetin alfa is a synthetic form of erythropoietin that stimulates red blood cell production and is commonly used to treat anemia in patients with chronic renal failure. By increasing red blood cell production, epoetin alfa helps raise hemoglobin levels in these patients. Pentoxifylline (Choice B) is not indicated for raising hemoglobin levels in chronic renal failure patients; it is a peripheral vasodilator used to improve blood flow. Estazolam (Choice C) is a benzodiazepine used for treating insomnia and has no role in raising hemoglobin levels. Dextromethorphan hydrobromide (Choice D) is a cough suppressant and is not used to raise hemoglobin levels in patients with chronic renal failure.

4. A woman is complaining that she feels like the room is spinning even though she is not moving. Which of the following is characteristic of benign positional vertigo?

Correct answer: C

Rationale: Benign positional vertigo is typically triggered by changes in head position, such as bending forward or turning over in bed. This change in position leads to brief episodes of vertigo, often associated with nystagmus, which is rapid, involuntary eye movements. Pupillary changes and headaches are not typical features of benign positional vertigo, making choices B and A incorrect. Nystagmus in benign positional vertigo usually stops when the eyes fixate on an object, so choice D is also incorrect.

5. A patient is being treated for active tuberculosis with ethambutol (Myambutol). The patient states to the nurse that he cannot identify the red and green on the traffic lights when he is driving. Based on this finding, what medical intervention is most appropriate?

Correct answer: A

Rationale: The correct answer is to assess for photosensitivity. Ethambutol can cause optic neuritis, leading to visual disturbances, including difficulty differentiating red and green colors. This is a sign of optic nerve damage and requires immediate evaluation. Discontinuing ethambutol may be necessary if optic neuritis is confirmed, but this decision should be made by a healthcare provider. Decreasing the dose of ethambutol may not address the visual changes. Administering vitamin B does not directly address the side effect caused by ethambutol.
