HESI Medical Surgical Assignment Exam
1. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:
- A. 85%
- B. 89%
- C. 95%
- D. 100%
Correct answer: C
Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.
2. A client with chronic pain is prescribed transdermal fentanyl (Duragesic) patches. Which instruction should the nurse include in the teaching plan?
- A. Apply the patch to a different site each time.
- B. Avoid using heating pads over the patch.
- C. Change the patch every 72 hours.
- D. Remove the old patch before applying the new one.
Correct answer: B
Rationale: Clients using transdermal fentanyl (Duragesic) patches should avoid using heating pads over the patch as heat can increase the release of the medication, potentially leading to overdose. The patch should be applied to a different site each time, changed every 72 hours, and the old patch should be removed before applying a new one to prevent accidental overdose or excessive drug absorption.
3. In the newborn nursery, the nurse admits a baby from labor and delivery who is suspected of having a congenital heart disease. Which finding helps to confirm this diagnosis?
- A. Pink lips and tongue with cyanotic hands and feet
- B. Respiration rate of 40 and heart rate of 144
- C. Centralized cyanosis and tachycardia when crying
- D. Desquamation from areas of cracked, parchment-like skin
Correct answer: C
Rationale: Centralized cyanosis and tachycardia are classic signs of congenital heart disease. Choice A is incorrect because cyanosis in the hands and feet is not specific to congenital heart disease. Choice B is incorrect as the vital signs provided are not specific indicators of congenital heart disease. Choice D is unrelated to the typical signs of congenital heart disease.
4. A client with a diagnosis of hyperthyroidism is being discharged. Which instruction should the nurse include in the discharge teaching?
- A. Avoid foods high in iodine.
- B. Take your medication with meals.
- C. Monitor your weight daily.
- D. Decrease your daily fluid intake.
Correct answer: A
Rationale: The correct answer is A: 'Avoid foods high in iodine.' Clients with hyperthyroidism should avoid foods high in iodine to prevent exacerbation of their condition. Iodine is an essential component in thyroid hormone production, and excessive iodine intake can worsen hyperthyroidism symptoms. Taking medication with meals (B) can interfere with the absorption of certain thyroid medications. Monitoring weight daily (C) is more relevant for conditions that may lead to weight changes like hypothyroidism. Decreasing fluid intake (D) is not a standard recommendation for hyperthyroidism unless specifically indicated by the healthcare provider.
5. A male client with acquired immunodeficiency syndrome (AIDS) develops cryptococcal meningitis and tells the nurse he does not want to be resuscitated if his breathing stops. What action should the nurse implement?
- A. Document the client's request in the medical record.
- B. Ask the client if this decision has been discussed with his healthcare provider.
- C. Inform the client that a written, notarized advance directive is required to withhold resuscitation efforts.
- D. Advise the client to designate a person to make healthcare decisions when the client is unable to do so.
Correct answer: B
Rationale: When a client expresses the desire to not be resuscitated, it is essential to inquire if this decision has been discussed with their healthcare provider. This is important to ensure that the client's wishes are appropriately documented and legally binding through the healthcare provider's guidance. It is crucial that healthcare decisions, especially those involving life-saving measures, are well-communicated and documented to respect the client's autonomy and ensure their wishes are honored. Option A is not the best action as it does not address the need to verify discussion with the healthcare provider. Option C is incorrect as it overemphasizes the need for a notarized advance directive, which may not be immediately feasible or necessary in this urgent situation. Option D is not the most appropriate action at this time since the immediate focus should be on clarifying if the decision has been communicated with the healthcare provider.
