1. Which biomolecule is responsible for the storage and transfer of genetic information?
- A. Carbohydrates
- B. Proteins
- C. Lipids
- D. Nucleic acids
Correct answer: D
Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
2. Which electrolyte imbalance is a potential side effect of diuretics?
- A. Hyperkalemia
- B. Hypercalcemia
- C. Hypomagnesemia
- D. Hypokalemia
Correct answer: D
Rationale: The correct answer is D, Hypokalemia. Diuretics commonly lead to hypokalemia, which is low potassium levels in the body. Hyperkalemia (choice A) is the opposite, indicating high potassium levels. Hypercalcemia (choice B) refers to elevated calcium levels, not typically associated with diuretics. Hypomagnesemia (choice C) is low magnesium levels and can also be a consequence of diuretic use, but potassium imbalance is more common.
3. Which electrolyte imbalance is most concerning in a patient on furosemide?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hyponatremia
- D. Hypercalcemia
Correct answer: B
Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.
4. How should a healthcare provider manage a patient with a history of hypertension who is non-compliant with medication?
- A. Educate the patient on the importance of medication
- B. Reassess the patient in 6 months
- C. Refer the patient to a specialist
- D. Discontinue the medication
Correct answer: A
Rationale: Educating the patient on the importance of medication is crucial when dealing with a patient who is non-compliant with their hypertension medication. By providing information about the significance of the medication in controlling blood pressure and preventing complications, the patient may be more motivated to adhere to the prescribed treatment. Reassessing the patient in 6 months (choice B) may lead to further deterioration of the patient's condition if non-compliance continues. Referring the patient to a specialist (choice C) may be necessary in some cases but should be preceded by efforts to improve compliance. Discontinuing the medication (choice D) without addressing the non-compliance issue can have serious health consequences for the patient.
5. A client has a new prescription for Lovastatin. Which of the following instructions should be included?
- A. Take this medication on an empty stomach.
- B. Take this medication in the morning.
- C. Take this medication at bedtime.
- D. Increase your intake of potassium-rich foods.
Correct answer: C
Rationale: Lovastatin should be taken at bedtime because cholesterol production in the liver is highest at night, making the medication more effective in reducing cholesterol levels. By taking it at bedtime, the medication aligns with the body's natural rhythm of cholesterol synthesis, optimizing its therapeutic effects.
