HESI CAT Exam 2022
1. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?
- A. To reduce abdominal pressure on the diaphragm
- B. To promote retraction of the intercostal accessory muscles of respiration
- C. To promote bronchodilation and effective airway clearance
- D. To decrease pressure on the medullary center which stimulates breathing
Correct answer: A
Rationale: Elevating the head of the bed to 30 degrees is done to reduce abdominal pressure on the diaphragm, aiding in lung expansion and oxygenation. This position helps improve respiratory mechanics by allowing the diaphragm to move more effectively. Choice B is incorrect as elevating the head of the bed does not directly promote retraction of the intercostal accessory muscles of respiration. Choice C is incorrect because although elevating the head of the bed can assist with airway clearance, its primary purpose in ARDS is to decrease pressure on the diaphragm. Choice D is incorrect because reducing pressure on the medullary center is not the main goal of elevating the head of the bed; the focus is on enhancing lung function and oxygen exchange.
2. A client with leukemia who is receiving myelosuppressive chemotherapy has a platelet count of 25,000/mm3. Which intervention is most important for the nurse to include in this client’s plan of care?
- A. Monitor for signs of activity intolerance
- B. Require visitors to wear respiratory masks
- C. Assess urine and stool for occult blood
- D. Obtain client’s temperature q4 hours
Correct answer: C
Rationale: The correct answer is to assess urine and stool for occult blood. With a low platelet count, there is an increased risk of bleeding. Monitoring for occult blood is essential to detect any signs of internal bleeding. Choices A, B, and D are not the priority interventions in this situation. While monitoring for signs of activity intolerance, requiring visitors to wear respiratory masks, and obtaining the client's temperature are important aspects of care, they are not as critical as assessing for occult blood in a client with a low platelet count.
3. The nurse is assessing a first-day postpartum client. Which finding is most indicative of a postpartum infection?
- A. Oral temperature of 100.2°F (37.9°C)
- B. Blood pressure of 122/74 mmHg
- C. Moderate amount of foul-smelling lochia
- D. White blood count of 19,000/mm³ (19x10^9/L SI units)
Correct answer: C
Rationale: A foul-smelling lochia is indicative of a postpartum infection, such as endometritis. Foul-smelling lochia suggests the presence of infection due to the breakdown of tissue by bacteria, leading to the malodor. An oral temperature elevation and an elevated white blood cell count are nonspecific and can be present in various conditions other than postpartum infections, making them less indicative. A blood pressure within normal limits is not typically associated with postpartum infections.
4. A client is being treated for minor injuries following an automobile accident in which the only other passenger was killed. The client asks the nurse, 'Is my friend who was in the car with me ok?' What response is best for the nurse to provide?
- A. I am sorry, but your friend was killed in the accident.
- B. Right now you need to concentrate on getting well.
- C. Was the passenger in the car your friend?
- D. I think your friend is going to be all right.
Correct answer: A
Rationale: The correct answer is A: 'I am sorry, but your friend was killed in the accident.' In this situation, honesty and compassion are essential. The nurse should provide the client with truthful information, acknowledging the client's need to know the reality of the situation. Choice B is dismissive and does not address the client's inquiry directly. Choice C is a deflecting question and does not offer the direct information the client is seeking. Choice D provides false reassurance, which is not appropriate in this circumstance where the reality needs to be communicated.
5. Parents who have one male child with sickle cell anemia are concerned about having more children with the disease. What client teaching should the nurse provide?
- A. All future children will be carriers, but will not necessarily have the disease
- B. There is a chance that each future child will have the disease
- C. Only male children cannot inherit the sickle cell disease trait
- D. Only one out of four of their children will definitely manifest the disease
Correct answer: B
Rationale: The correct answer is B. Each child has a 25% chance of having sickle cell anemia if both parents are carriers of the trait. Choice A is incorrect because not all future children will be carriers; some may have the disease. Choice C is incorrect as both male and female children can inherit the sickle cell disease trait. Choice D is incorrect as the chance is not fixed at one out of four; each child has an independent 25% chance of having the disease.
