1. What is the hallmark sign of intussusception?

• A. Mucus-like stools
• B. Currant jelly-like stools
• C. Tarry, black stools
• D. Green, soft stools

Correct answer: B

Rationale: The hallmark sign of intussusception is currant jelly-like stools, which result from the mixture of blood and mucus in the stool due to the sloughing of intestinal mucosa. Mucus-like stools (Choice A) are not typically associated with intussusception. Tarry, black stools (Choice C) are characteristic of gastrointestinal bleeding higher up in the gastrointestinal tract, such as from a peptic ulcer. Green, soft stools (Choice D) are more indicative of rapid transit through the intestines, possibly due to dietary factors or infections such as gastroenteritis.

2. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?

• A. Low oxygen levels are present in the blood.
• B. High levels of carbon dioxide have accumulated in the blood.
• C. Increased bicarbonate levels are causing alkalosis.
• D. Respiratory rate is increased, causing hyperventilation.

Correct answer: B

Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.

3. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?

• A. 100 mL/hour.
• B. 125 mL/hour.
• C. 133 mL/hour.
• D. 150 mL/hour.

Correct answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.

4. A new mother asks the clinic nurse if she must continue giving her baby nystatin for thrush since the white lesions on his tongue have disappeared. What response by the nurse is most appropriate?

• A. No. When the lesions have disappeared, you may stop the nystatin.
• B. Yes. You should continue it for the full 7 days.
• C. No. Thrush is a self-limiting disorder, and nystatin is given for complete treatment.
• D. Yes. The medication should be refilled for a second week of therapy.

Correct answer: B

Rationale: The correct answer is B because nystatin should be given for the full 7 days even if the lesions are no longer present. Continuing the treatment for the prescribed duration ensures complete eradication of the fungal infection. Choice A is incorrect as stopping the medication prematurely may lead to the reoccurrence of thrush. Choice C is inaccurate as nystatin is not just for comfort but for effective treatment. Choice D is incorrect as refilling the medication for a second week without medical advice may lead to unnecessary prolonged use and potential side effects.

5. During a home visit, the nurse assesses the skin of a client with eczema who reports that an exacerbation of symptoms has occurred during the last week. Which information is most useful in determining the possible cause of the symptoms?

• A. An old friend with eczema came for a visit.
• B. Recently received an influenza immunization.
• C. A grandson and his new dog recently visited.
• D. Corticosteroid cream was applied to eczema.

Correct answer: C

Rationale: The correct answer is C. Contact with the grandson's new dog could have introduced new allergens or irritants, exacerbating the eczema symptoms. Choice A is unrelated to the exacerbation of symptoms. Choice B, receiving an influenza immunization, is unlikely to directly cause an exacerbation of eczema symptoms. Choice D, applying corticosteroid cream, is a common treatment for eczema and would not likely be the cause of the exacerbation.
