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: Irritability is indeed an early sign that a tracheostomy client may require suctioning. When a tracheostomy client becomes irritable, it can indicate that there is a need for suctioning to clear the airway. Bradycardia (choice A) refers to a slow heart rate and is not typically a direct indication for suctioning. Hypotension (choice C) indicates low blood pressure and is not specifically related to the need for suctioning. Decreased respiratory rate (choice D) can be a sign of respiratory distress, but irritability is a more direct and early indication of the need for suctioning in a tracheostomy client.

Correct Answer: D

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: 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: B

Rationale: The correct answer is B. Clients with type 2 diabetes should aim for the same pregnancy weight gain as those without diabetes. Option A is too restrictive and may not be appropriate for a healthy pregnancy. Option C also imposes a specific limit without considering individual needs. Option D is incorrect as excessive weight gain can lead to complications in pregnancy, especially for individuals with diabetes.
