Rationale: It is crucial to withhold all opioids, including Morphine, if the client's respiratory rate is 12/min or less, and promptly inform the healthcare provider. Respiratory depression is a significant adverse effect of opioids, and administering them when the respiratory rate is already compromised can further suppress breathing, leading to potentially life-threatening complications.

Rationale: The correct answer is to avoid drinking grapefruit juice when taking Atorvastatin. Grapefruit juice can interfere with the metabolism of Atorvastatin, leading to increased blood levels of the medication, which can result in a higher risk of adverse effects, such as muscle pain and liver damage. It is important for the client to follow this instruction to ensure the safe and effective use of Atorvastatin.

Correct Answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: (750 mL / 6 hr) = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse dextrose 5% in water (D5W) over 6 hours.

Correct Answer: A

Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases, as tachycardia can indicate a severe adverse reaction to the medication.
