Nursing Elites

1. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

2. A client recovering from a urologic procedure is being assessed by a nurse. Which assessment finding indicates an obstruction of urine flow?

• A. Severe pain
• B. Overflow incontinence
• C. Hypotension
• D. Blood-tinged urine

Correct answer: B

Rationale: The correct answer is 'B: Overflow incontinence.' The most common manifestation of urethral stricture after a urologic procedure is obstruction of urine flow. This obstruction can lead to overflow incontinence, which is the involuntary loss of urine when the bladder is distended. Severe pain is not typically associated with an obstruction of urine flow. Hypotension is unrelated to this issue. Blood-tinged urine is not a direct indication of an obstruction of urine flow but may indicate other conditions like trauma or infection.

3. The client with peripheral vascular disease (PVD) and a history of heart failure may have a low tolerance for exercise due to:

• A. Decreased blood flow.
• B. Increased blood flow.
• C. Decreased pain.
• D. Increased blood viscosity.

Correct answer: A

Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.

4. The healthcare provider caring for a patient who will receive penicillin to treat an infection asks the patient about previous drug reactions. The patient reports having had a rash when taking amoxicillin (Amoxil). The healthcare provider will contact the provider to

• A. discuss giving a smaller dose of penicillin.
• B. discuss using erythromycin (E-mycin) instead of penicillin.
• C. request an order for diphenhydramine (Benadryl).
• D. suggest that the patient receive cefuroxime (Ceftin).

Correct answer: B

Rationale: When a patient reports a previous rash with amoxicillin, which is a type of penicillin, there is a concern for a penicillin allergy. In such cases, using an alternative antibiotic like erythromycin, which is not a penicillin, is the appropriate approach to avoid potential cross-reactivity and allergic reactions. Giving smaller doses of penicillin does not address the underlying allergy issue and can still lead to severe hypersensitivity reactions. Diphenhydramine (Benadryl) is used to manage allergic reactions but should not be the first choice in changing the antibiotic. While some patients allergic to penicillins may also be allergic to cephalosporins like cefuroxime, it is not the best immediate alternative in this scenario.

5. An emergency department nurse assesses a client with a history of urinary incontinence who presents with extreme dry mouth, constipation, and an inability to void. Which question should the nurse ask first?

• A. Are you drinking plenty of water?
• B. What medications are you taking?
• C. Have you tried laxatives or enemas?
• D. Has this type of thing ever happened before?

Correct answer: B

Rationale: In this scenario, the client's symptoms of dry mouth, constipation, and inability to void are indicative of anticholinergic side effects, which can be caused by medications like propantheline (Pro-Banthine) commonly used to treat incontinence. The first question the nurse should ask is about the client's medications to determine if they are taking anticholinergic drugs. This information is crucial as it can help differentiate between a simple side effect or a potential overdose. Asking about water intake (Choice A) may be relevant later but is not the priority in this situation. Questioning about laxatives or enemas (Choice C) and past occurrences (Choice D) are not as pertinent initially as identifying the client's current medication status.
