Correct Answer: A

Rationale: By determining the client's usual bedtime routine and incorporating these rituals into the care plan, the nurse can help the client fall asleep faster and improve the quality of care without compromising safety. This approach respects the client's individual needs and preferences. In contrast, options B, C, and D do not address the client's sleep issue effectively and may even compromise the client's safety or standard of care. Option B fails to address the underlying problem of the client's sleep disturbance, while option C reduces the frequency of assessments, which can impact the timely identification of changes in the client's condition. Option D focuses on pain medication and daytime napping, which are not directly related to the client's current sleep difficulties.

Correct Answer: D

Rationale: When a postoperative client's respiratory rate increases, it is essential to determine the underlying cause. Pain, anxiety, and fluid accumulation in the lungs can lead to tachypnea (increased respiratory rate). Therefore, the priority intervention is to assess if pain is the contributing factor. Encouraging increased ambulation may worsen oxygen desaturation in a client with a rising respiratory rate. Offering a high-carbohydrate snack is not indicated as it can increase carbon metabolism; instead, consider providing an alternative energy source like Pulmocare liquid supplement. Forcing fluids may exacerbate respiratory congestion in a client with a compromised cardiopulmonary system, potentially leading to fluid overload. Therefore, determining the role of pain in tachypnea is crucial for appropriate management.

Correct Answer: B

Rationale: To calculate the volume to administer, use the formula: (Volume to administer = (Ordered Dose × Volume on hand) / Dose on hand). In this case, it would be (4 mg × 1 mL) / 5 mg = 0.8 mL. Therefore, the nurse should administer 0.8 mL of diazepam. Choice A (0.2 mL) is incorrect because it miscalculates the dosage. Choice C (1.25 mL) and Choice D (2.0 mL) are incorrect as they do not align with the correct calculation based on the ordered dose and available concentration. The correct answer, 0.8 mL, is derived from accurate dosage calculation and aligns with the formula for IV medication administration, ensuring the safe and effective delivery of the medication to the client.

Correct Answer: B

Rationale: When assisting a patient with right-sided weakness using a gait belt, the caregiver must stand on the weak side of the patient to provide optimal support and security. By standing on the weak side and holding the gait belt from the back, the caregiver can effectively prevent falls and guide the patient's movements. This position allows for better control over the patient's balance. Standing on the strong side (option A) does not offer the necessary support if the patient leans towards the weak side. Standing behind the patient and holding both sides of the gait belt (option C) does not provide focused support to the weak side. Standing slightly in front and to the right (option D) may not offer adequate assistance to prevent falls on the weak side, making it an incorrect choice.

Correct Answer: B

Rationale: When changing the route of administration from PO to IV, the absorption process is bypassed, leading to a more rapid onset of action of the medication and consequently a quicker effect. Choices A, C, and D are incorrect. Increased drug tolerance and higher doses are not typical outcomes of changing the route of administration. Protein binding does not increase with a change to IV administration; rather, it is the bioavailability and onset of action that are affected. Moreover, an increased therapeutic index reduces the risk of drug toxicity, contrary to what is stated in choice D.
