Community Health HESI Study Guide
1. The milk code aims to ensure that:
- A. the public receives accurate information about breastmilk and breastfeeding
- B. health workers do not provide samples of infant formula to pregnant women or mothers of infants
- C. companies consistently recognize the superiority of breastmilk
- D. health workers do not accept any incentives from milk companies
Correct answer: C
Rationale: The correct answer is C because the milk code emphasizes that companies should always acknowledge the superiority of breastmilk over formula. Choice A is incorrect because the focus is not on the public receiving information, but rather on companies recognizing breastmilk's superiority. Choice B is incorrect as it addresses health workers' actions, not the companies' behavior. Choice D is incorrect as the milk code is primarily concerned with regulating companies' practices, not health workers' acceptance of incentives.
2. A nurse manager is reviewing isolation guidelines with a newly licensed nurse. Which of the following statements by the newly licensed nurse indicates understanding of isolation guidelines?
- A. I will have a client who is on airborne precautions wear a mask when out of their room.
- B. I will wear an N95 respirator mask for a client who is on droplet precautions.
- C. I will place a client who has compromised immunity in a negative-pressure airflow room.
- D. I will instruct visitors to wear a mask when visiting a client who is on contact precautions.
Correct answer: A
Rationale: The correct answer is A. Having a client on airborne precautions wear a mask when out of their room is appropriate to prevent the spread of infection. Choice B is incorrect because the healthcare provider, not the client, wears an N95 respirator mask for a client on droplet precautions. Choice C is incorrect because negative-pressure airflow rooms are used for clients with airborne infections, not compromised immunity. Choice D is incorrect because visitors, not clients, should wear a mask when visiting a client on contact precautions.
3. A client is admitted to the postoperative surgical unit with two test tubes after a left lobectomy. The nurse observed that the chambers are set at the prescribed suction of 20 cm water pressure, and tidying occurs with respirations and bubbling. What action should the nurse implement?
- A. Clamp the chest tube to see if the bubbling activity stops
- B. Notify the registered nurse of the observed bubbling
- C. Maintain system integrity to promote lung reexpansion
- D. Apply an occlusive dressing to the chest
Correct answer: C
Rationale: Maintaining system integrity is essential to promote lung reexpansion in postoperative patients with chest tubes. Clamping the chest tube abruptly can lead to tension pneumothorax, a life-threatening condition. The bubbling observed is a normal sign indicating that the system is functioning correctly, as it allows the drainage of air or fluid from the pleural space. Notifying the registered nurse may be necessary if there are significant concerns or changes observed, but the immediate action should be to ensure system integrity and lung reexpansion.
4. A client with Addison's disease started taking hydrocortisone in a divided daily dose last week. It is most important for the nurse to monitor which serum laboratory value?
- A. Osmolarity
- B. Glucose
- C. Albumin
- D. Platelets
Correct answer: B
Rationale: The correct answer is B: Glucose. Hydrocortisone can lead to increased blood glucose levels, so monitoring glucose is crucial to assess for hyperglycemia, a common side effect of corticosteroid therapy. Monitoring osmolarity (choice A) is not typically indicated in this scenario. Albumin (choice C) and platelets (choice D) are not directly affected by hydrocortisone therapy and are not the primary focus of monitoring in this case.
5. A client undergoing hemodialysis for chronic kidney disease is taking the medication erythropoietin. The nurse should reinforce instructions to explain for which reason this medication is prescribed?
- A. This drug prevents infections associated with dialysis.
- B. This drug prevents deep vein thrombosis in older clients.
- C. This drug helps stimulate the production of red blood cells.
- D. This drug helps balance the level of phosphorus in the body.
Correct answer: C
Rationale: Erythropoietin is prescribed to stimulate the production of red blood cells. Clients undergoing hemodialysis often develop anemia due to end-stage renal disease. Erythropoietin helps correct this anemia by stimulating red blood cell production. It is not used to prevent infections associated with dialysis, prevent deep vein thrombosis, or balance phosphorus levels in the body.
