A client is admitted with heart failure (HF) and left ventricular hypertrophy. Which intervention is most likely to avert development of cardiomegaly and improve myocardial contractility?
Teach about compliance to reduce blood pressure.
Provide rest periods and portable oxygen.
Maintain continuous monitoring of heart rate and rhythm.
Administer nitroglycerin daily.
The Correct Answer is A
A. This is the most likely intervention to avert cardiomegaly and improve myocardial contractility. By reducing blood pressure, the heart doesn't have to work as hard to pump blood, which can help prevent the heart from enlarging (cardiomegaly) and improve its ability to contract effectively.
B. While rest and oxygen can help manage symptoms of heart failure, they do not directly address the underlying issue of increased cardiac workload and hypertrophy.
C. Monitoring heart rate and rhythm is important for assessing the patient's condition, but it does not prevent cardiomegaly or improve contractility.
D. Nitroglycerin is used to treat acute symptoms of heart failure, such as chest pain, but it is not a long- term solution for preventing cardiomegaly or improving contractility.

Correct Answer is B
Explanation
A. Weight gain is a common symptom of hypothyroidism but it is not an immediate threat to life. It can be managed with diet and medication.
B. Hypoventilation, or decreased respiratory rate, can lead to hypoxemia (low oxygen levels in the blood) and hypercapnia (increased carbon dioxide levels in the blood). These conditions can rapidly deteriorate into a respiratory crisis and require immediate intervention.
C. Cold intolerance is a common symptom of hypothyroidism but is not an immediate threat to life. It can be managed with warm clothing and a warm environment.
D. Lethargy is another common symptom of hypothyroidism but is not an immediate threat to life. It can be managed with medication and lifestyle changes.
8. The nurse reviews discharge instructions with a client
Correct Answer is ["B","C","D","F"]
Explanation
A. Vomiting is not a common side effect of phenytoin but could occur in some patients. It’s more likely a
reaction to the medication rather than a frequent side effect.
B. Phenytoin can affect blood coagulation. It may interfere with vitamin K metabolism, which can alter coagulation pathways and increase the risk of bleeding or bruising. Monitoring for signs of bleeding or changes in clotting status is important, particularly in patients on long-term therapy.
C. Visual disturbances, including nystagmus (involuntary eye movements), double vision, or blurred vision, can occur with phenytoin use. This side effect is related to the medication’s impact on the nervous system.
D. Drowsiness is a common side effect of many antiepileptic drugs, including phenytoin. It can affect the client’s alertness and overall level of consciousness, making it important for the nurse to monitor and address any related safety concerns.
E. Aphasia, or difficulty with language and speech, is not a typical side effect of phenytoin. While phenytoin affects the central nervous system, aphasia is not commonly reported with its use.
F. Ataxia, or lack of coordination and unsteady movements, is a known side effect of phenytoin. This occurs due to its effects on the nervous system and can impair motor skills and coordination.
