1. What lab value should be prioritized in a patient with HIV?

A. CD4 T-cell count below 180 cells/mm3
B. White blood cell count
C. Serum albumin levels
D. Hemoglobin levels

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it indicates the level of immunocompromise. A count below 180 cells/mm3 signifies severe immunocompromise and an increased risk of opportunistic infections. Choices B, C, and D are not the priority lab values in HIV management. While white blood cell count, serum albumin levels, and hemoglobin levels are important, they do not directly reflect the immune status and progression of HIV as the CD4 T-cell count does.

2. What is a characteristic sign of hypokalemia on an ECG?

A. Flattened T waves
B. ST elevation
C. Prominent U waves
D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

3. What should be monitored in a patient with diabetes insipidus?

A. Monitor urine specific gravity for values below 1.005
B. Monitor for increased thirst
C. Monitor serum albumin levels
D. Monitor blood pressure closely

Correct answer: A

Rationale: In a patient with diabetes insipidus, monitoring urine specific gravity for values below 1.005 is crucial. Low urine specific gravity indicates excessive water loss, a key characteristic of diabetes insipidus. Monitoring for increased thirst (choice B) may be a symptom presented by the patient, but it does not directly reflect the condition's severity. Monitoring serum albumin levels (choice C) is not typically associated with diabetes insipidus. Monitoring blood pressure closely (choice D) is not a primary concern in diabetes insipidus unless severe dehydration leads to hypotension.

4. What dietary recommendations should be provided to a patient with GERD?

A. Avoid mint and spicy foods
B. Eat large meals before bed
C. Consume liquids with meals
D. Avoid foods high in potassium

Correct answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid mint and spicy foods. These types of foods can trigger acid reflux and worsen GERD symptoms. Choice B is incorrect as eating large meals before bed can increase the likelihood of acid reflux due to increased pressure on the lower esophageal sphincter. Choice C is also incorrect as consuming liquids with meals can cause distension in the stomach, potentially leading to reflux. Choice D is not directly related to GERD, as foods high in potassium are generally healthy and not specifically problematic for GERD patients.

5. 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?

A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis

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.
