Correct Answer: B

Rationale: The correct instruction to include in the discharge teaching for a client following cataract extraction is to 'Avoid straining during stool passage, bending, or lifting heavy objects.' This is crucial to prevent increased intraocular pressure after surgery, which can be harmful. Reading with direct lighting can strain the eyes but is not the primary concern post-cataract surgery. Irrigating the conjunctiva before applying antibiotic ointment is not a standard practice and may not be necessary. While limiting sunlight exposure is important for eye protection, it is secondary to avoiding activities that can increase intraocular pressure.

Correct Answer: B

Rationale: In this scenario, if the nurse's finger is stuck with the needle before administering the injection, the correct action is to prepare the medication using a new syringe. This step is crucial to prevent contamination and ensure the safety of the patient. Going to the emergency room to have blood drawn is unnecessary and does not address the immediate issue of contamination. Applying clean gloves is important for infection control but does not address the potential contamination from the needlestick. Reviewing the medical history in the client's chart is important for overall patient care but is not the priority in this situation where immediate action is required to prevent harm.

Correct Answer: B

Rationale: The correct intervention is to schedule a follow-up appointment for an outpatient psychosocial assessment. This option addresses the client's concerns and provides support for managing stress and preventing future crises, which is crucial for the client's long-term care. Administering antianxiety medication before providing discharge instructions (Choice A) may not effectively address the underlying concerns. Obtaining a blood cortisol level before discharge (Choice C) is important but not the priority in this situation. Encouraging the client to remain in the hospital for a few more days (Choice D) is not the best course of action as it may not address the client's anxiety and could potentially lead to other issues.

Correct Answer: C

Rationale: The correct answer is C. Some salt substitutes can be high in potassium, which may not be suitable for clients with heart failure. Option A is correct as using lemon juice and herbs for flavoring is a good low-sodium alternative. Option B is also correct as canned soups and frozen dinners are typically high in sodium content. Option D is correct as checking food labels for sodium content is an essential part of managing a low-sodium diet. Therefore, the client's statement about using salt substitutes needs correction as it can introduce high levels of potassium, which may not be recommended for individuals with heart failure.

Correct Answer: A

Rationale: The correct answer is A: Ask the client about gastrointestinal pain. The effectiveness of a proton pump inhibitor (PPI) is best evaluated by assessing the relief of gastrointestinal symptoms, such as heartburn, acid reflux, or stomach pain. These medications work by reducing the production of stomach acid, so improvement in these symptoms indicates the effectiveness of the PPI. Choices B, C, and D are incorrect because they do not directly reflect the effectiveness of a PPI. Measuring fluid intake and output, monitoring serum electrolyte levels, and auscultating for bowel sounds are important for assessing hydration status, electrolyte balance, and gastrointestinal motility, respectively. However, they are not specific to evaluating PPI effectiveness.
