Correct Answer: B

Rationale: The correct answer is to inject enoxaparin subcutaneously at a 45-degree angle. This angle helps ensure proper delivery of the medication into the subcutaneous tissue. Option A (Inject at a 90-degree angle) is incorrect because subcutaneous injections are usually given at a shallower angle. Option C (Massage the injection site after administering) is incorrect as massaging the site can cause bruising and should generally be avoided. Option D (Use a longer needle) is incorrect as using a longer needle is unnecessary and may increase the risk of injecting the medication too deeply.

Correct Answer: A

Rationale: The correct answer is the hospital ethics committee. This committee is specifically designed to address and resolve ethical conflicts in patient care. It comprises professionals from various disciplines who can provide guidance and support in navigating ethical dilemmas. Choice B, the quality improvement committee, focuses on enhancing the quality of care provided but may not be equipped to handle ethical conflicts. Choice C, the chaplain, offers spiritual and emotional support but may not have the expertise to resolve ethical dilemmas. Choice D, the director of nursing, is responsible for nursing operations and may not be the appropriate resource for addressing ethical conflicts.

Correct Answer: A

Rationale: In an SBAR report, key information such as the client's do-not-resuscitate (DNR) status should be included as it directly impacts the client's care and treatment plan. Choices B and C are important details but may not be as critical for immediate care planning during the shift change. Choice D, the client having Medicare insurance, is important for billing purposes but does not directly impact the client's immediate care needs.

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 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.
