Correct Answer: C

Rationale: The correct answer is C, 'Lack of health literacy.' The nurse's inability to follow the medication regimen suggests she may lack health literacy, meaning she may not fully understand how to manage her own health care. Choice A, 'Early cognitive impairment,' is not supported by the information provided in the question as there is no mention of cognitive decline. Choice B, 'Lack of motivation,' is less likely as the behavior is more indicative of a knowledge deficit rather than a lack of drive. Choice D, 'Worsening health state,' is also less likely as the behavior described does not directly imply a worsening health condition but rather a misunderstanding or lack of knowledge on managing health.

Correct Answer: C

Rationale: When contractions occur every 45 seconds with a high fetal heart rate, it indicates uterine hyperstimulation and fetal distress. In this situation, the oxytocin infusion should be discontinued immediately to prevent further complications. Increasing or maintaining the infusion would worsen the hyperstimulation and distress. Decreasing the infusion may not be sufficient to address the current situation and could still lead to complications.

Correct Answer: B

Rationale: The correct answer is to take the medication with a full glass of water. Alendronate should be taken with a full glass of water to prevent esophageal irritation. Additionally, the client should remain upright for 30 minutes after taking it to prevent potential adverse effects. Choice A is incorrect because alendronate should not be taken at bedtime, but rather in the morning on an empty stomach. Choice C is incorrect because alendronate should be taken on an empty stomach, not with food. Choice D is incorrect because the client should remain upright, not lie down, for 30 minutes after taking the medication.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to discontinue the oxytocin infusion. The client is experiencing uterine hyperstimulation, which can lead to fetal distress and complications. By stopping the oxytocin, the nurse can help regulate contractions and prevent harm to the fetus. Increasing the oxytocin infusion would exacerbate the issue by further intensifying contractions. Applying an internal fetal monitor may be necessary for closer monitoring but is not the immediate action required. Administering an analgesic is not appropriate in this scenario as the primary concern is addressing the uterine hyperstimulation caused by oxytocin.

Correct Answer: C

Rationale: The correct answer is C. Low back pain during a blood transfusion is a classic sign of a transfusion reaction, specifically a transfusion-associated circulatory overload (TACO) or hemolytic reaction, both of which require immediate attention to prevent serious complications. Assessing this client first is crucial to ensure prompt intervention. Choices A, B, and D do not indicate immediate life-threatening complications and can be addressed after the client experiencing low back pain during a blood transfusion is stabilized.
