Correct Answer: A

Rationale: The correct nursing interventions for a patient with hypertension involve monitoring blood pressure and educating the patient about lifestyle changes. These interventions help in managing hypertension by keeping track of the patient's blood pressure readings and empowering them with knowledge to make lifestyle modifications such as adopting a healthy diet, regular exercise, stress management, and avoiding smoking and excessive alcohol consumption. Administering antihypertensive medications (choice B) is typically done by a healthcare provider rather than a nurse. While regular monitoring of blood pressure (choice C) is important, administering diuretics is a specific medical intervention that should be prescribed by a healthcare provider. Monitoring blood glucose (choice D) is more relevant for patients with diabetes rather than hypertension.

Correct Answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

Correct Answer: D

Rationale: Managing pain in a post-operative patient requires a multimodal approach, which includes both pharmacological and non-pharmacological strategies. Administering analgesics as prescribed helps in controlling pain pharmacologically. Encouraging deep breathing exercises can aid in pain management by promoting relaxation and reducing anxiety. Providing distractions, such as music or activities, can help divert the patient's attention from pain. Therefore, all the given options are essential components of an effective pain management plan for post-operative patients.

Correct Answer: D

Rationale: The correct answer is 'Muscle weakness.' Hypokalemia is characterized by low potassium levels, which can lead to muscle weakness due to impaired muscle function. Choices A, B, and C are incorrect findings associated with other medical conditions and not typically expected in hypokalemia. Muscle stiffness is more commonly associated with conditions like tetany or muscle cramps, bradycardia is more commonly associated with issues like heart block or hypothyroidism, and hyperreflexia is more commonly seen in conditions like hyperthyroidism or spinal cord injuries.

Correct Answer: B

Rationale: Monitoring cardiac status is crucial during the acute phase of Kawasaki disease because of the potential for coronary artery complications. Acetaminophen may be used for fever management but is not the priority intervention. Antibiotics are not indicated as Kawasaki disease is not caused by a bacterial infection. Providing stimulation in the playroom is important for the child's emotional well-being but does not address the immediate physiological concern of cardiac monitoring.
