Correct Answer: B

Rationale: The correct answer is B because a decrease in blood pressure is an expected outcome when propranolol, a beta-blocker, is effectively managing hyperthyroidism. Propranolol helps control symptoms such as tachycardia and hypertension associated with hyperthyroidism. Choices A, C, and D are incorrect because weight gain, increased energy, and an increased respiratory rate are not direct indicators of propranolol's effectiveness in treating hyperthyroidism.

Correct Answer: C

Rationale: A respiratory rate of 8/min is a significant adverse effect of morphine that indicates respiratory depression, which requires immediate intervention to prevent further complications. The client may not be effectively ventilating, leading to hypoxia and respiratory acidosis. Option A is less concerning as being drowsy but responsive is a common side effect of morphine. Option B indicates decreased oxygen saturation, which is also a concern but not as severe as respiratory depression. Option D is important but not as critical as the potential respiratory compromise indicated by the low respiratory rate.

Correct Answer: B

Rationale: The correct nursing interventions for a patient with pneumonia include monitoring lung sounds and respiratory rate to assess the effectiveness of treatment and the patient's respiratory status. Providing fluids and rest (Choice A) can be supportive measures but are not specific nursing interventions for pneumonia. Encouraging coughing and deep breathing exercises (Choice C) can be helpful for airway clearance but may not be appropriate for all patients with pneumonia. Administering antibiotics and providing oxygen therapy (Choice D) are medical interventions rather than nursing interventions.

Correct Answer: B

Rationale: The correct answer is B. Tai chi is a recognized complementary health practice for stress reduction. Scheduling time for a new client to continue tai chi practice aligns with supporting holistic care. Choice A is incorrect because reporting a client's use of echinacea as a contraindication to aspirin therapy is not necessary without further context or evidence of interactions. Choice C is wrong because yoga can indeed be effective in reducing manifestations of menopause. Choice D is also incorrect because while cranberry juice is known to help prevent urinary tract infections, it is not typically used to treat existing infections.

Correct Answer: D

Rationale: The recommended approach for handling aggressive behavior in a mental health setting is to maintain eye contact, offer clear choices, and set boundaries. This approach can help de-escalate the situation by establishing communication and structure. Choice A is incorrect as encouraging physical activity may not be suitable during an aggressive episode. Choice B is incorrect because avoiding eye contact can hinder communication and resolution. Choice C is also incorrect as pharmacological interventions should not be the immediate go-to method for managing aggression unless absolutely necessary.
