1. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is experiencing respiratory alkalosis due to hyperventilation. Hyperventilation leads to excessive loss of carbon dioxide, causing a decrease in hydrogen ion concentration and an increase in pH levels. Choices A, C, and D are incorrect. Respiratory acidosis is characterized by high PaCO2 and low pH. Metabolic acidosis is associated with low HCO3- levels and low pH. Metabolic alkalosis is marked by high HCO3- levels and high pH. In this case, the ABG results indicate respiratory alkalosis.

2. When providing discharge teaching to a patient who underwent cataract surgery, what should the patient avoid?

Correct answer: A

Rationale: The correct answer is to avoid NSAIDs. Nonsteroidal anti-inflammatory drugs (NSAIDs) can increase the risk of bleeding after cataract surgery due to their anticoagulant properties. Bright lights (choice B) are not contraindicated post-cataract surgery unless the patient experiences discomfort or sensitivity. Alcohol consumption (choice C) is generally not restricted after cataract surgery, but moderation is recommended. Phosphorus-rich foods (choice D) are not directly related to cataract surgery postoperative care.

3. What is the primary concern in a patient with a low CD4 T-cell count in HIV?

Correct answer: A

Rationale: The correct answer is A: Increased risk of infection. In HIV patients with a low CD4 T-cell count, the primary concern is the increased susceptibility to infections due to compromised immunity. This compromised immune system can lead to various infections, making infection control crucial. Choice B, increased risk of bleeding, is not directly associated with a low CD4 count in HIV. Option C, decreased immunity leading to opportunistic infections, conveys a similar concern as the correct answer but lacks specificity. Choice D, increased risk of cardiac complications, is not typically the primary concern in HIV patients with a low CD4 count, as infections and opportunistic diseases pose more immediate threats to health.

4. What dietary recommendations should be given to a patient with pre-dialysis end-stage kidney disease?

Correct answer: A

Rationale: The correct recommendation for a patient with pre-dialysis end-stage kidney disease is to reduce phosphorus intake to 700 mg/day. High phosphorus levels can lead to complications in such patients. Increasing sodium intake (Choice B) is generally not recommended due to its association with hypertension and fluid retention. While protein is essential, increasing protein intake (Choice C) in kidney disease can be harmful as it can lead to increased waste products that the kidneys may struggle to excrete. Increasing potassium intake (Choice D) is not advisable as well, as patients with kidney disease may already have difficulty excreting potassium, leading to hyperkalemia.

5. What intervention is needed for a patient with a chest tube and an air leak?

Correct answer: A

Rationale: The correct intervention for a patient with a chest tube and an air leak is to tighten the connections of the chest tube system. This step helps prevent air leaks and ensures the proper functioning of the chest tube. Choice B, replacing the chest tube, is not necessary as tightening the connections should be attempted first. Clamping the chest tube (Choice C) is not recommended as it can lead to complications by obstructing the drainage system. Continuing to monitor the chest tube (Choice D) without taking action may result in worsening of the air leak. Therefore, the priority intervention is to tighten the connections of the chest tube system.
