A patient diagnosed with hypokalemia is at risk for which condition?
- A. Cardiac dysrhythmias
- B. Muscle weakness
- C. Seizures
- D. Bradycardia
Correct Answer: A
Rationale: Patients diagnosed with hypokalemia are at risk for cardiac dysrhythmias due to low potassium levels. Hypokalemia can lead to abnormalities in the electrical conduction system of the heart, potentially causing irregular heart rhythms. Muscle weakness (Choice B) is a symptom commonly associated with hypokalemia, but the question asks about conditions the patient is at risk for, not specific symptoms. Seizures (Choice C) are not typically associated with hypokalemia; they are more commonly linked with conditions such as epilepsy. Bradycardia (Choice D) refers to a slow heart rate, which is not a typical risk associated with hypokalemia; instead, tachycardia (fast heart rate) is more commonly observed in patients with low potassium levels.

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.
What medication should be administered first for wheezing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Cromolyn via nebulizer
- C. Methylprednisolone IV
- D. Aminophylline 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 quickly opens the airways by relaxing the muscles around the airways. Cromolyn (choice B) is used more for prevention rather than immediate relief of symptoms. Methylprednisolone (choice C) and Aminophylline (choice D) are not the first-line treatments for acute wheezing due to an allergic reaction.
What are the expected findings in a patient with hypokalemia?
- A. Cardiac dysrhythmias
- B. Seizures and confusion
- C. Bradycardia
- D. Muscle weakness
Correct Answer: A
Rationale: The correct answer is A: Cardiac dysrhythmias. Hypokalemia is commonly associated with cardiac dysrhythmias due to the role potassium plays in maintaining proper electrical conduction in the heart. Choices B, C, and D are incorrect. While hypokalemia can lead to muscle weakness, the most critical and life-threatening manifestation is cardiac dysrhythmias. Seizures and confusion are more commonly associated with other electrolyte imbalances, such as hyponatremia. Bradycardia is not a typical finding in hypokalemia, as it tends to cause tachycardia or other arrhythmias.
What dietary recommendations should a patient with GERD follow?
- A. Avoid mint and spicy foods
- B. Consume liquids between meals
- C. Eat three large meals per day
- D. Drink milk as a snack
Correct Answer: A
Rationale: Patients with GERD should follow dietary recommendations to manage their symptoms effectively. Choice A, 'Avoid mint and spicy foods,' is the correct answer. Mint and spicy foods can trigger acid reflux and worsen GERD symptoms. Choice B, 'Consume liquids between meals,' is not the best recommendation as consuming liquids during meals can worsen GERD symptoms by increasing stomach pressure. Choice C, 'Eat three large meals per day,' is incorrect as large meals can exacerbate GERD symptoms; instead, smaller, more frequent meals are recommended. Choice D, 'Drink milk as a snack,' is not ideal as full-fat dairy products like milk can trigger acid reflux in some individuals. Therefore, the best recommendation for a patient with GERD is to avoid mint and spicy foods.
What is the primary concern for a patient with a CD4 T-cell count below 180 cells/mm³?
- A. Increased risk of severe infection
- B. Increased risk of anemia
- C. Increased risk of bleeding
- D. Increased risk of dehydration
Correct Answer: A
Rationale: A CD4 T-cell count below 180 cells/mm³ indicates a severely immunocompromised state, leading to an increased risk of severe infection. In individuals with low CD4 counts, the immune system is significantly weakened, making them more susceptible to opportunistic infections. Anemia (choice B), bleeding (choice C), and dehydration (choice D) are not the primary concerns associated with a low CD4 T-cell count. While these conditions may occur as secondary effects or complications, the primary focus is on preventing and managing severe infections in patients with severely compromised immune systems.
