1. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?
- A. Administer potassium supplements orally.
- B. Increase the client's dietary potassium intake.
- C. Inform the healthcare provider of the need for potassium replacement.
- D. Monitor the client's ECG continuously.
Correct answer: C
Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.
2. A client who is receiving general anesthesia begins to demonstrate symptoms of malignant hyperthermia. Which intervention should the perioperative nurse prepare to implement first?
- A. Ensure patency of an indwelling catheter and measure hourly intake and output.
- B. Prepare for cessation of the anesthesia and the surgical procedure.
- C. Obtain specimens of ABGs and serum electrolytes.
- D. Initiate cooling measures using iced normal saline by nasogastric lavage.
Correct answer: B
Rationale: The correct answer is B: Prepare for cessation of the anesthesia and the surgical procedure. Malignant hyperthermia is a severe reaction to certain medications used during general anesthesia. The immediate intervention to manage malignant hyperthermia is to stop the triggering agents, which include anesthesia and surgery. Ensuring patency of an indwelling catheter and measuring intake and output, obtaining specimens of ABGs and serum electrolytes, and initiating cooling measures are important interventions but should follow the immediate action of stopping the anesthesia and surgery to address the life-threatening condition of malignant hyperthermia.
3. Which is a priority nursing intervention for the cognitively impaired child?
- A. The family will provide good nutrition.
- B. The family will provide loving interactions.
- C. Stimulation will improve.
- D. There will be contact with peers.
Correct answer: B
Rationale: The correct answer is B because nursing interventions for cognitively impaired children prioritize promoting loving interactions with family. This support helps in creating a nurturing environment that contributes to the child's well-being and development. Choice A is not the priority as good nutrition, though important, may not address the immediate emotional and social needs of the child. Choice C is vague and does not specify how stimulation will be provided. Choice D, contact with peers, is also valuable but not as crucial as the primary relationships and interactions within the family unit for a cognitively impaired child.
4. What should the nurse assess in an infant who has been diagnosed with hypertrophic pyloric stenosis?
- A. A history of diarrhea following each feeding
- B. Gastric pain evidenced by vigorous crying
- C. Poor appetite due to a poor sucking reflex
- D. An olive-shaped mass right of the midline
Correct answer: D
Rationale: The correct answer is D. In hypertrophic pyloric stenosis, a key assessment finding is an olive-shaped mass in the right upper quadrant of the abdomen, to the right of the midline. This mass is palpable and represents the hypertrophied pyloric muscle. Choices A, B, and C are incorrect because although they may be present in infants with feeding problems, the definitive assessment for hypertrophic pyloric stenosis is the presence of an olive-shaped mass on the right side of the abdomen, not a history of diarrhea, gastric pain, or poor appetite.
5. 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.
