Correct Answer: A

Rationale: The correct answer is A: Peripheral neuropathy. Didanosine (ddl) can cause peripheral neuropathy as a side effect, which can exacerbate existing neuropathy. The client's history of peripheral neuropathy warrants caution with this drug to prevent further nerve damage. Incorrect choices: B: Hypertension - Didanosine is not contraindicated in hypertension. C: Diabetes mellitus - While monitoring blood sugar levels is important, didanosine does not directly affect diabetes. D: Asthma - Didanosine does not have a significant impact on asthma. In summary, the client's pre-existing peripheral neuropathy makes it important to exercise caution with didanosine to avoid worsening this condition.

Correct Answer: B

Rationale: The correct answer is B because rifampin can cause discoloration of bodily fluids, including tears. If clients wear contact lenses, they need to be informed that the lenses may become colored due to this medication. This is important for the client's awareness and to prevent any potential harm to their eyes. A: Taking medication with meals is not necessary for rifampin administration. C: Avoiding wearing glasses is not relevant to rifampin treatment. D: Avoiding tuna, aged cheese, and red wine is not specifically related to rifampin use.

Correct Answer: A

Rationale: The correct answer is A: Postural hypotension. This condition is characterized by a drop in blood pressure upon standing, leading to dizziness. The client's symptoms of dizziness upon standing, along with nosebleeds and blurred vision, are indicative of low blood pressure. Postural hypertension (B) is not a recognized medical condition; White coat hypertension (C) refers to elevated blood pressure readings in a medical setting due to anxiety; White coat hypotension (D) is not a recognized medical condition.

Correct Answer: A

Rationale: The presence of redness, swelling, and induration at the wound site are indicative of infection. Redness and swelling suggest inflammation, while induration indicates tissue hardening and can be a sign of infection spreading. Infection can delay healing and lead to complications if not treated promptly. Evisceration refers to wound opening with protrusion of internal organs, not indicated by the symptoms. Dehiscence is the partial or complete separation of wound layers, not represented by the symptoms. Hemorrhage involves excessive bleeding, which is not described in the scenario. Therefore, choice A is correct as it aligns with the signs observed and is the most appropriate response for the situation.

Correct Answer: C

Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to gather comprehensive data about the patient's health status, including vital signs, physical appearance, and potential health issues. It provides valuable information for developing an individualized care plan. Reviewing literature (A) is important but not for establishing a patient's database. Checking orders (B) and ordering medications (D) are part of the treatment process and do not directly contribute to establishing the initial patient database.
