Correct Answer: A

Rationale: The correct answer is to use sunblock or protective clothing when outdoors. Methotrexate can cause photosensitivity, making the child more prone to sunburns and skin damage. Therefore, advising the parents to protect their child's skin from direct sunlight exposure is crucial. Choice B is incorrect because exposing the child to direct sunlight without protection can worsen the photosensitivity caused by methotrexate. Choice C is incorrect as obtaining vaccinations is generally avoided during chemotherapy due to the child's compromised immune system. Choice D is incorrect as commercial mouthwash may contain alcohol, which can be irritating to the child's oral mucosa, especially during chemotherapy.

Correct Answer: C

Rationale: After a traumatic experience like a spontaneous abortion, it is crucial for the nurse to provide emotional support. Expressing sorrow for the client's grief and offering to sit with her demonstrates empathy and allows the client to process her emotions. Options A and B focus on future possibilities and medical interventions, which may not be immediately appropriate. Option D, while important for monitoring the client's physical status, does not address the client's emotional needs at that moment.

Correct Answer: A

Rationale: Difficulty swallowing (dysphagia) can indicate complications such as aspiration risk, which is common after a stroke due to impaired swallowing reflexes. It poses a serious threat to the client's respiratory system. Options B, C, and D are less likely to indicate immediate complications post-stroke. A slight headache is a common complaint and may not necessarily indicate a complication. High blood pressure is a known risk factor for strokes but may not be an immediate post-stroke complication unless it is severely elevated. Muscle weakness on one side is a common sign of stroke but may not directly indicate a new complication.

Correct Answer: A

Rationale: During a severe asthma exacerbation, the nurse's priority is to administer a rescue inhaler immediately. This action helps open the airways and improve breathing, which is crucial in managing the exacerbation. Choice B, preparing for intubation, would be considered if the client's condition deteriorates and they are unable to maintain adequate oxygenation even after using the rescue inhaler. Encouraging deep breathing exercises (Choice C) may not be appropriate during a severe exacerbation as the client may struggle to breathe. While monitoring oxygen saturation levels (Choice D) is important, the immediate administration of a rescue inhaler takes precedence to address the acute breathing difficulty.

Correct Answer: C

Rationale: The correct answer is C: 'To stimulate red blood cell production.' Epoetin alfa, such as Epogen, is used to treat anemia by stimulating red blood cell production in clients with chronic kidney disease. This medication helps increase hemoglobin levels and reduce the need for blood transfusions. Option A, 'To reduce the risk of bleeding,' is incorrect as epoetin alfa does not directly impact bleeding risk. Option B, 'To lower blood pressure,' is incorrect as epoetin alfa is not indicated for blood pressure management. Option D, 'To increase appetite,' is also incorrect as the primary goal of epoetin alfa is related to improving anemia by boosting red blood cell production.
