Rationale: The correct first action when preparing to administer a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to prevent transfusion reactions and complications. Option A is incorrect because blood transfusions should not be administered through an IV push due to the risk of rapid infusion and adverse reactions. Option C is incorrect because blood should be transfused at room temperature, not body temperature. Option D is incorrect because it is not necessary for the client to eat before a blood transfusion.

Rationale: In resolving ethical dilemmas, it is essential to identify possible solutions to address the client care dilemma effectively. Option A, 'Ensure client autonomy only,' is not comprehensive enough to resolve complex ethical issues. Option B, 'Consider only medical benefits,' overlooks other important factors beyond medical benefits that are involved in ethical decision-making. Option C, 'Ensure clear communication among the health care team,' is important but may not be sufficient on its own to resolve the ethical dilemma. Therefore, the most effective strategy among the given options is to identify possible solutions to navigate through the ethical dilemma.

Correct Answer: A

Rationale: The correct answer is A: 'Heart disease and stroke.' Untreated hypertension can lead to various complications, including heart disease and stroke. These are common outcomes of long-term high blood pressure. Choice B, 'Kidney failure and vision loss,' is incorrect as kidney failure and vision loss are more commonly associated with diabetic complications rather than untreated hypertension. Choice C, 'Pulmonary embolism and arrhythmias,' while serious, are not among the primary complications of untreated hypertension. Choice D, 'Blood clots and gastrointestinal bleeding,' are not typical complications of untreated hypertension but can occur due to other conditions such as blood clotting disorders or gastrointestinal diseases.

Correct Answer: B

Rationale: The correct answer is to wear gloves when applying the transdermal nicotine patch to prevent the nurse from absorbing nicotine through the skin. Choice A is incorrect because shaving hairy areas of skin is not necessary for applying a transdermal patch. Choice C is incorrect as transdermal patches should be applied immediately after removal from the protective pouch, not necessarily within 1 hour. Choice D is incorrect because the previous patch should be disposed of properly following institutional guidelines, not placed in a tissue.

Correct Answer: A

Rationale: For a patient with diarrhea, the priority is to manage dehydration by providing oral fluids and monitoring stool consistency. Option B suggesting administering antidiarrheal medications is not recommended as it may prolong the infection by preventing the body from expelling the infectious agent. Option C is incorrect because antibiotics are not routinely indicated for diarrhea unless there is a specific bacterial infection. Option D is not the most appropriate initial intervention for managing diarrhea since a low-fiber diet may not provide adequate nutrition for the patient or help resolve the underlying cause of diarrhea.
