Nursing Elites

1. A 50-milliliter (ml) bolus of normal saline fluid is ordered by the physician. The physician wants it to infuse in 30 minutes. The nurse should set the pump rate at:

• A. 100 ml per hour for one hour.
• B. 60 ml per hour for one-half hour
• C. 120 ml per hour for one hour.
• D. 50 ml per hour for one hour.

Correct answer: A

Rationale: To infuse a 50 ml bolus in 30 minutes, the rate should be calculated as follows: 50 ml / 30 min = 100 ml per hour. Therefore, the correct answer is to set the pump rate at 100 ml per hour for one hour. Choice A is the correct rate based on the calculation. Choices B, C, and D all provide incorrect rates that do not match the physician's order. Choice B would only deliver 30 ml in 30 minutes, not the ordered 50 ml. Choice C would deliver 120 ml in one hour, which is 20 ml more than ordered. Choice D would only provide 25 ml over 30 minutes, not the full 50 ml prescribed.

2. During a well-baby check of a 6-month-old infant, the nurse notes abrasions and petechiae of the palate. The nurse should:

• A. inquire about the possibility of sexual abuse.
• B. ask about the types of foods the child is eating.
• C. request to see the type of bottle used for feedings.
• D. question the parent about objects the child plays with.

Correct answer: A

Rationale: The correct answer is to inquire about the possibility of sexual abuse. Injuries to the soft palate such as bruising, abrasions, and petechiae can be signs of sexual abuse in infants. While oral sex may not leave significant physical evidence, these findings should raise suspicion. Option A is correct as it focuses on addressing potential abuse. Options B, C, and D are incorrect because the child's diet, the type of bottle used for feedings, and play objects are not likely related to the observed injuries. The presence of oral injuries suggests considering sexual abuse rather than other factors.

3. A 5-year-old is admitted to the unit following a tonsillectomy. Which of the following would indicate a complication of the surgery?

• A. Decreased appetite
• B. A low-grade fever
• C. Chest congestion
• D. Constant swallowing

Correct answer: D

Rationale: A complication of a tonsillectomy is bleeding, and constant swallowing may indicate bleeding. Decreased appetite is expected after a tonsillectomy, as is a low-grade fever; thus, answers A and B are incorrect. Chest congestion, as mentioned in answer C, is not typical of tonsillectomy complications, making it an incorrect choice.

4. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

5. The physician prescribes captopril (Capoten) 25mg po tid for the client with hypertension. Which of the following adverse reactions can occur with administration of Capoten?

• A. Tinnitus
• B. Persistent cough
• C. Muscle weakness
• D. Diarrhea

Correct answer: B

Rationale: A persistent cough might be related to an adverse reaction to captopril (Capoten). Tinnitus (choice A) and diarrhea (choice D) are not commonly associated adverse reactions of captopril. Muscle weakness (choice C) might occur initially but is not considered a common adverse effect of captopril. Therefore, the correct answer is B, persistent cough, as it is a known adverse reaction to captopril.
