Correct Answer: C

Rationale: Monitoring serum electrolyte levels would be the most appropriate action for a client admitted with a cardiac dysrhythmia. Electrolyte imbalances, particularly potassium and magnesium, can lead to cardiac dysrhythmias. Therefore, it is crucial to monitor and maintain proper electrolyte levels to prevent or manage dysrhythmias. Restricting fluids, encouraging bedrest, or instructing in a low-fat diet are not the priority actions for managing a cardiac dysrhythmia.

Correct Answer: A

Rationale: A. Excessive sweating: Children with congestive heart failure (CHF) may experience excessive sweating as their bodies work harder to keep up with the demands of the heart, leading to increased sympathetic tone and perspiration.

Correct Answer: A

Rationale: As individuals age, there is a natural increase in systolic blood pressure (the top number in a blood pressure reading). This rise is attributed to factors such as arterial stiffness, reduced compliance of blood vessels, and decreased elasticity of the arteries. This increase in systolic blood pressure with age is considered a significant risk factor for hypertension in older adults. Hypertension is commonly defined as having a systolic blood pressure of 140 mmHg or higher and/or a diastolic blood pressure of 90 mmHg or higher. Therefore, the age-related increase in systolic blood pressure contributes to the overall risk of developing hypertension in the elderly population.

Correct Answer: A

Rationale: Jerking movements in the face, arms, or legs can be a sign of seizures, which can occur as a result of a stroke in infants. This question is important to assess whether the infant may have experienced any seizure activity, which could indicate a potential stroke. It helps the nurse gather more information to understand the infant's symptoms and assess the possibility of a stroke event.
