The nurse identifies that the goal of decreasing the cardiac workload for a client receiving atenolol 25 mg PO BID for unstable angina is met when the client has:
An increase in urine output.
Less dyspnea with activity.
A blood pressure of 120/80 mmHg.
A heart rate of 65 per minute.
The Correct Answer is D
Choice a reason:
An increase in urine output can be a sign of improved kidney function or the effect of medications, but it is not a direct indicator of reduced cardiac workload. Atenolol, a beta-blocker, primarily reduces the heart rate and myocardial oxygen demand, not urine output.
Choice b reason:
Less dyspnea with activity suggests improved cardiovascular efficiency, but it is not a specific measure of cardiac workload. Dyspnea can be influenced by respiratory conditions and is not solely determined by cardiac function.
Choice c reason:
A blood pressure of 120/80 mmHg is considered optimal for most adults and indicates good control of hypertension. However, it does not specifically reflect the cardiac workload, which is more directly affected by heart rate and myocardial oxygen demand.
Choice d reason:
A heart rate of 65 per minute is a clear indicator that atenolol is effective in reducing cardiac workload. Atenolol decreases the heart rate, which in turn reduces myocardial oxygen demand and the overall workload on the heart. This is particularly important for patients with unstable angina, where reducing the heart's workload can prevent angina attacks and potential myocardial infarction.

Correct Answer is C
Explanation
Choice A reason:
Assisting the client to turn by having them grasp the side rails is not recommended immediately following a laminectomy and spinal fusion. This action could place undue stress on the surgical site and potentially disrupt the healing process. Postoperative care typically involves minimizing movement of the spine to prevent complications.
Choice B reason:
Maintaining strict bedrest for 48 hours postoperatively is not a current standard of care following a laminectomy and spinal fusion. Early ambulation, as tolerated, is encouraged to promote circulation and prevent complications such as deep vein thrombosis (DVT) and pulmonary embolism (PE).
Choice C reason:
Assessing the client's pain level and administering pain medication as needed is a critical nursing intervention postoperatively. Effective pain management is essential for promoting patient comfort, facilitating early mobilization, and preventing complications. Pain assessment and management should be tailored to the individual's needs and carried out with regular monitoring.
Choice D reason:
Placing the client in the prone position is not typically advised following a laminectomy and spinal fusion, as it may put pressure on the surgical site and cause discomfort. The preferred position is usually on the back or occasionally on the side with proper support, depending on the surgeon's protocol and the client's comfort.
Correct Answer is B
Explanation
Choice A reason:
Magnesium sulfate is used in the management of severe preeclampsia primarily for seizure prophylaxis. One of the key side effects of magnesium sulfate is its impact on neuromuscular transmission, leading to diminished deep-tendon reflexes as serum magnesium levels rise. The therapeutic range for anticonvulsant prophylaxis is typically between 5-8 mg/dL. Reflexes may begin to diminish when serum levels reach 8-12 mg/dL, indicating potential magnesium toxicity. Therefore, diminished reflexes are a warning sign to reassess the infusion rate and possibly reduce or discontinue the medication.
Choice B reason:
A respiratory rate of 16 breaths per minute falls within the normal adult range and suggests that the client's respiratory system is not being adversely affected by the magnesium sulfate infusion. Respiratory rate is a critical parameter to monitor during magnesium sulfate therapy, as respiratory depression is a serious side effect of magnesium toxicity. Maintaining a normal respiratory rate indicates that it is safe to continue the infusion at the current rate.
Choice C reason:
While a urine output of 50 mL/hr is on the lower end of the normal range, it is still considered adequate for most adults. In the setting of magnesium sulfate therapy for severe preeclampsia, maintaining adequate urine output is essential for ensuring that the kidneys can excrete the magnesium to prevent accumulation and toxicity. If urine output decreases significantly, it may necessitate reevaluation of the infusion rate or additional interventions to support renal function.
Choice D reason:
A heart rate of 56 beats per minute is slightly bradycardic but may not be clinically significant if the client is asymptomatic. However, magnesium has a direct effect on cardiac function, and high levels can lead to bradycardia and other cardiac conduction abnormalities. It is important to monitor the client's heart rate and rhythm during magnesium sulfate therapy to detect any early signs of cardiac involvement due to magnesium toxicity.
