A patient is prescribed an angiotensin-converting enzyme (ACE) inhibitor for heart failure. Which laboratory parameter should the nurse monitor closely during ACE inhibitor therapy?

Correct Answer: A

Rationale: The nurse should monitor serum potassium levels closely during ACE inhibitor therapy because ACE inhibitors can lead to an increase in serum potassium levels, known as hyperkalemia. ACE inhibitors block the conversion of angiotensin I to angiotensin II, which in turn decreases aldosterone secretion. Aldosterone normally acts in the kidneys to reabsorb sodium and water and excrete potassium. Therefore, when aldosterone secretion is decreased due to ACE inhibitor therapy, there can be an increase in potassium retention, potentially leading to hyperkalemia. Monitoring serum potassium levels is essential to prevent complications associated with hyperkalemia, such as cardiac arrhythmias.

Correct Answer: B

Rationale: Antipsychotic medications can cause metabolic side effects, including hyperglycemia (high blood sugar). Patients with bipolar disorder who are prescribed antipsychotic medications are at risk for developing new-onset diabetes or exacerbating preexisting diabetes. Monitoring blood glucose levels is essential to detect hyperglycemia early and prevent complications such as diabetic ketoacidosis. While hypertension, hypotension, and hypernatremia are possible side effects of certain medications, they are not typically associated with antipsychotic medications commonly used in the management of bipolar disorder. Hyperglycemia is a serious concern in this population due to the risk of developing diabetes or worsening of existing diabetes.

Correct Answer: B

Rationale: The nurse's priority action when noticing an abnormal heart rhythm on the patient's cardiac monitor during surgery is to assess the patient's vital signs and symptoms. This is important because the nurse needs to gather more information about the patient's condition to determine the significance of the abnormal rhythm and the potential impact on the patient's health. By assessing the vital signs and symptoms, the nurse can obtain a more complete picture of the situation and make informed decisions about the next steps in caring for the patient. Once the assessment is done, appropriate actions such as administering medication or notifying the anesthesiologist can be taken based on the findings.

Correct Answer: C

Rationale: If the nurse observes an unusual odor emanating from the surgical site during surgery, it is important to inform the surgeon immediately and assess for signs of infection. Changes in odor can sometimes be an early sign of infection, which requires prompt attention and intervention. By communicating with the surgeon and conducting a thorough assessment, the nurse can help ensure the timely detection and management of any potential complications, such as infection, that may be affecting the patient's surgical outcome. Prompt action in response to unusual observations is crucial to maintaining patient safety and well-being during surgical procedures.

Correct Answer: B

Rationale: Offering reassurance and encouragement to the patient demonstrates therapeutic communication by the nurse. In this situation, the nurse shows empathy and understanding towards the patient's concerns about the upcoming surgical procedure, which can help alleviate anxiety and build trust. Providing reassurance and encouragement can help the patient feel supported and understood, creating a positive and therapeutic interaction between the nurse and the patient. This approach fosters open communication and helps establish a therapeutic nurse-patient relationship, which is essential for effective patient care.
