What should a healthcare provider monitor for in a patient with HIV and a CD4 T-cell count below 180 cells/mm3?
- A. Monitor for signs of infection
- B. Monitor for anemia
- C. Monitor for dehydration
- D. Monitor for bleeding
Correct Answer: A
Rationale: A CD4 T-cell count below 180 cells/mm3 indicates severe immunocompromise in a patient with HIV. Monitoring for signs of infection is crucial because the patient is at high risk of developing opportunistic infections. Anemia (choice B), dehydration (choice C), and bleeding (choice D) are not directly associated with a low CD4 T-cell count in patients with HIV.

A nurse administers insulin for a misread glucose level. What should the nurse monitor for?
- A. Monitor for hypoglycemia
- B. Monitor for hyperglycemia
- C. Monitor for hyperkalemia
- D. Document the incident
Correct Answer: A
Rationale: When a nurse administers insulin for a misread glucose level, they should monitor for hypoglycemia. Insulin lowers blood sugar levels, so the patient may experience hypoglycemia if given insulin unnecessarily. Monitoring for hypoglycemia involves observing for symptoms such as shakiness, sweating, dizziness, confusion, and palpitations. Choices B and C are incorrect because administering insulin for a misread glucose level would lower blood sugar levels, resulting in hypoglycemia, not hyperglycemia or hyperkalemia. Choice D is not the immediate priority; the focus should be on patient safety and monitoring for potential adverse effects of the unnecessary insulin.
A patient who experienced an acute episode of gastritis should avoid which type of foods?
- A. Avoid foods high in potassium
- B. Avoid foods high in sodium
- C. Increase exercise to reduce stress
- D. Drink milk as a snack
Correct Answer: A
Rationale: The correct answer is A: Avoid foods high in potassium. Potassium-rich foods can exacerbate gastritis symptoms by irritating the stomach lining. Sodium (choice B) is not directly related to gastritis symptoms. Increasing exercise (choice C) can be beneficial for overall health but may not directly impact gastritis. Drinking milk (choice D) can provide temporary relief for some individuals with gastritis due to its coating effect, but it is not a universal recommendation as it can worsen symptoms in some cases.
The nurse misread a patient's glucose as 210 mg/dL instead of 120 mg/dL and administered the insulin dose for a reading over 200 mg/dL. What is the priority action?
- A. Administer glucose IV
- B. Monitor for hyperglycemia
- C. Monitor for hypoglycemia
- D. Document the incident
Correct Answer: C
Rationale: The priority action is to monitor the patient for signs of hypoglycemia as the nurse administered excess insulin due to misreading the glucose level. Administering glucose IV (Choice A) is not the immediate priority when dealing with hypoglycemia. Monitoring for hyperglycemia (Choice B) is not the correct action as the insulin was administered for a higher glucose reading. Documenting the incident (Choice D) is important but not the priority when the patient's safety is at risk due to possible hypoglycemia.
What ECG changes are seen in hypokalemia?
- A. Flattened T waves on the ECG
- B. Elevated ST segments on the ECG
- C. Widened QRS complex
- D. Prominent U waves on the ECG
Correct Answer: A
Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.
What is the first medication to give to a patient with wheezing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Methylprednisolone 100 mg IV
- C. Cromolyn 20 mg via nebulizer
- D. Aminophylline 500 mg IV
Correct Answer: A
Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it is a fast-acting bronchodilator that helps to quickly open the airways, providing immediate relief of symptoms. Choice B, Methylprednisolone 100 mg IV, is a corticosteroid used for its anti-inflammatory effects but is not the initial medication for acute wheezing in an allergic reaction. Choice C, Cromolyn 20 mg via nebulizer, is a mast cell stabilizer that can be used for prevention but is not the first choice for acute symptom relief. Choice D, Aminophylline 500 mg IV, is a bronchodilator with a narrow therapeutic window and more side effects compared to Albuterol, making it a less preferred option as the initial treatment.
