Correct Answer: C

Rationale: The correct answer is C: 'Monitor for liver function.' Duloxetine is an antidepressant medication, not an antipsychotic, so choice A is incorrect. One of the common side effects of duloxetine is weight gain, making choice B incorrect. Choice D, stating that duloxetine has no side effects, is inaccurate as all medications have the potential for side effects. Monitoring liver function is crucial with duloxetine because it can impact liver function, emphasizing the importance of regular checks to ensure the client's safety.

Correct Answer: C

Rationale: The correct answer is C, 'Living will.' A living will is a legal document that outlines an individual's preferences for life-sustaining medical treatment if they become unable to make decisions. Choice A, 'Do Not Resuscitate,' specifically refers to a directive that instructs healthcare providers not to perform CPR. Choice B, 'Informed consent,' pertains to a patient's right to be informed about and consent to medical treatment. Choice D, 'Durable power of attorney for health care,' involves appointing someone to make healthcare decisions on behalf of an individual when they are unable to do so.

Correct Answer: A

Rationale: The correct answer is A: 90-degree angle. The ventrogluteal site is preferred for intramuscular injections because it is away from major nerves and blood vessels. Administering the injection at a 90-degree angle ensures that the medication reaches deep into the muscle tissue, allowing for proper absorption of the drug. Choice B, 60-degree angle, is incorrect as it is not the recommended angle for the ventrogluteal site. Choice C, 75-degree angle, and Choice D, 45-degree angle, are also incorrect as they are not the appropriate angles for administering an intramuscular injection using the ventrogluteal site.

Correct Answer: A

Rationale: Corrected Rationale: When administering warfarin, it is crucial to verify the patient's INR levels. INR monitoring is essential to ensure that the patient is receiving the correct dose of warfarin for their condition and to minimize the risk of bleeding. Choices B, C, and D are incorrect because administering warfarin with food, monitoring blood glucose levels, and assessing liver function are not directly related to the safe administration and monitoring of warfarin therapy.

Correct Answer: B

Rationale: The correct answer is B. Applying clean dressings over blood-saturated ones and holding pressure helps to control bleeding and prevent tissue disruption. Removing blood-saturated dressings can cause further damage by disrupting the forming clot. Elevating the wound above heart level is beneficial to reduce swelling, but it is not the best immediate action for a blood-saturated dressing. Leaving the wound open to air can increase the risk of infection and slow down the healing process.
