1. Which of the following is the drug of choice to decrease uric acid levels?
- A. prednisone (Colisone)
- B. allopurinol (Zyloprim)
- C. indomethacin (Indocin)
- D. hydrochlorothiazide (HydroDiuril)
Correct answer: B
Rationale: Allopurinol is the correct drug to decrease uric acid levels as it is used to treat gout by reducing uric acid formation. Prednisone is a corticosteroid that decreases inflammation, not uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, not specifically used to reduce uric acid levels. Hydrochlorothiazide is a thiazide diuretic primarily used for treating hypertension and edema, not for reducing uric acid levels.
2. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?
- A. Ca
- B. K
- C. Na
- D. Cl
Correct answer: B
Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.
3. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?
- A. PaO2 90 mm Hg
- B. Bicarbonate 15 mEq/L
- C. CO2 47 mm Hg
- D. pH 7.34
Correct answer: B
Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.
4. A young female teenager describes a brutal assault and rape to the nurse on duty. Which of the following actions should the nurse take first?
- A. Check with the case manager on duty about possible police intervention.
- B. Provide an environment of concern and emotional stabilization.
- C. Clean the patient's wounds with normal saline and gauze.
- D. Refer the patient to a counselor specializing in trauma.
Correct answer: B
Rationale: In a situation where a patient describes a brutal assault and rape, the first priority should be to provide emotional support and create a safe and supportive environment. This helps the patient feel secure and cared for, which is crucial for their well-being at that moment. Checking with the case manager about police intervention should come after ensuring the patient's immediate emotional needs are addressed. Cleaning the patient's wounds, though important, can be secondary to providing emotional stabilization. Referring the patient to a counselor specializing in trauma is also crucial for long-term support, but the immediate focus should be on providing emotional support and stability.
5. Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:
- A. an antihyperglycemic agent.
- B. a hypoglycemic agent.
- C. an insulin analogue.
- D. a pancreatic alpha cell stimulant
Correct answer: A
Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.
