A nurse is applying a nitroglycerin transdermal patch for a client who has angina. Which of the following actions should the nurse take?

Choice A Reason:
Weight gain of 0.7 kg (1.5 lb) in 24 hours is not recommendable. While sudden weight gain can indicate fluid retention, it is not a direct contraindication for administering digoxin. However, it might indicate worsening heart failure, which needs attention, but it doesn't specifically necessitate withholding digoxin.
Choice B Reason:
Urinary output 30 mL/hr is not recommendable. A low urinary output might indicate decreased kidney perfusion or renal issues. While monitoring urinary output is important, it is not a direct reason to withhold digoxin unless it's coupled with severe renal impairment or an acute kidney injury.
For a client receiving digoxin, certain findings would warrant withholding the medication due to potential complications. Among the options provided:
Choice C Reason:
Pulse rate 56/min is the correct recommendation. A low pulse rate (bradycardia), especially below 60 beats per minute, is a reason to withhold digoxin. Digoxin can further decrease the heart rate, potentially leading to excessive bradycardia or heart block. The nurse should hold the medication and consult with the healthcare provider to determine the appropriate action.
Choice D Reason:
BP 160/90 mm Hg is not recommendable. Elevated blood pressure alone is not a direct contraindication for administering digoxin to a patient with heart failure. Digoxin is not primarily used for controlling blood pressure; its use is more focused on managing heart rate and contractility in heart failure patients.

Choice A Reason:
Ondansetron is incorrect. Ondansetron is an anti-nausea medication commonly used in cancer patients to manage nausea and vomiting, often caused by chemotherapy. It's not typically contraindicated or known to interact significantly with morphine administered via a PCA pump. This combination is often used to manage both pain and associated symptoms in cancer patients.
Choice B Reason:
Acetaminophen is incorrect. Acetaminophen is a pain reliever and fever reducer that doesn't typically interact significantly with morphine administered via a PCA pump. It's often used concurrently with other pain medications to manage discomfort in cancer patients. There isn't a known significant interaction between acetaminophen and morphine when used appropriately.
Choice C Reason:
Nalbuphine is correct. Nalbuphine is an opioid analgesic, similar to morphine, and administering it concurrently with morphine could potentially lead to opioid overdose or increased risk of opioid-related side effects such as respiratory depression. Thus, it's crucial to clarify with the provider whether there might be a potential interaction or if both medications are indeed necessary in this specific clinical scenario.
Choice D Reason:
Insulin glargine is incorrect. Insulin glargine is a long-acting insulin used to manage blood sugar levels in individuals with diabetes. While its interaction with morphine isn't typically a concern, it's essential to monitor blood sugar levels closely in individuals receiving opioids like morphine, as opioids can affect glucose metabolism and may necessitate adjustments in insulin dosage.
