Correct Answer: C

Rationale: The correct answer is C. Regular exercise is an essential component in managing hypertension. Exercising for at least 30 minutes a day, at least 5 days a week, can help control blood pressure. Checking blood pressure regularly (choice A) is important, but not as indicative of understanding the teaching as the commitment to regular exercise. Avoiding foods high in potassium (choice B) is not a typical recommendation for managing hypertension. Taking medication only when feeling dizzy (choice D) is incorrect and potentially dangerous; medications should be taken as prescribed by the healthcare provider.

Correct Answer: D

Rationale: The correct answer is D because viewing the newborn's actions as uncooperative may indicate the client is struggling to bond, requiring intervention. Choices A, B, and C do not raise concerns about the bonding process between the client and the newborn. Holding the newborn in an en face position is a positive interaction. Asking the father to change the newborn's diaper involves family participation in care. Requesting the nurse to take the newborn to the nursery so she can rest is a valid request for maternal self-care.

Correct Answer: B

Rationale: The correct answer is B: Loss of interest in usual activities. Clients with PTSD often exhibit symptoms such as numbing, which can manifest as a loss of interest in activities they once enjoyed. Choice A, dependence on family and friends, is more indicative of seeking support rather than a direct symptom of PTSD. Choice C, ritualistic behavior, is more commonly associated with conditions like obsessive-compulsive disorder. Choice D, passive-aggressive behavior, is not a typical finding in clients with PTSD.

Correct Answer: C

Rationale: In a patient with a history of angina experiencing chest pain, the priority action for the nurse is to obtain a 12-lead ECG. This helps in assessing for myocardial infarction, a serious condition that requires immediate attention. Administering oxygen, nitroglycerin, or notifying the healthcare provider can be important interventions but obtaining the ECG comes first to determine the presence of myocardial infarction and guide further management.

Correct Answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, ensuring adequate oxygenation is the priority. Administering oxygen helps improve oxygen levels, which is crucial for the patient's well-being. Repositioning the patient, administering bronchodilators, or giving IV fluids are important interventions in certain situations, but when a patient is in respiratory distress, providing oxygen takes precedence over other actions.
