1. What is the primary nursing intervention for a patient experiencing an acute asthma attack?
- A. Administering bronchodilators.
- B. Administering antibiotics.
- C. Administering IV fluids.
- D. Administering corticosteroids.
Correct answer: A
Rationale: The correct answer is administering bronchodilators. During an acute asthma attack, the primary goal is to relieve airway constriction and bronchospasm to improve breathing. Bronchodilators, such as short-acting beta-agonists, are the cornerstone of treatment as they help dilate the airways quickly. Administering antibiotics (choice B) is not indicated unless there is an underlying bacterial infection. Administering IV fluids (choice C) may be necessary in some cases, but it is not the primary intervention for an acute asthma attack. Administering corticosteroids (choice D) is often used as an adjunct therapy to reduce airway inflammation, but it is not the primary intervention during the acute phase of an asthma attack.
2. Which is a characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections?
- A. Sulfonamides are bactericidal.
- B. Sulfonamides are synthetic compounds.
- C. Sulfonamides have antifungal and antiviral properties.
- D. Sulfonamides increase bacterial synthesis of folic acid.
Correct answer: B
Rationale: The characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections is that sulfonamides are synthetic compounds, not derived from biologic substances. Choice A is incorrect because sulfonamides are bacteriostatic, not bactericidal. Choice C is incorrect because sulfonamides do not have antifungal and antiviral properties. Choice D is incorrect because sulfonamides act by inhibiting bacterial synthesis of folic acid, not increasing it.
3. In a patient with diabetes mellitus, which of the following is a sign of hypoglycemia?
- A. Polydipsia.
- B. Polyuria.
- C. Sweating.
- D. Dry skin.
Correct answer: C
Rationale: Sweating is a common sign of hypoglycemia in diabetic patients. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can cause sweating as a response to the perceived danger. Polydipsia (excessive thirst) and polyuria (excessive urination) are actually more commonly associated with hyperglycemia, not hypoglycemia. Dry skin is not typically a sign of hypoglycemia.
4. A nurse teaches a client who is recovering from a nephrectomy secondary to kidney trauma. Which statement should the nurse include in this client’s teaching?
- A. Since you only have one kidney, a salt and fluid restriction is required.
- B. Your therapy will include hemodialysis while you recover.
- C. Medication will be prescribed to control your high blood pressure.
- D. You need to avoid participating in contact sports like football.
Correct answer: D
Rationale: Clients with one kidney need to avoid contact sports because the kidneys are easily injured. The client will not be required to restrict salt and fluids, end up on dialysis, or have new hypertension because of the nephrectomy.
5. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?
- A. To broaden the antibacterial spectrum.
- B. To decrease bacterial resistance.
- C. To improve the taste.
- D. To minimize toxic effects.
Correct answer: B
Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.
