HESI CAT Exam 2022
1. The nurse is providing care for a client with chronic obstructive pulmonary disease (COPD). Which intervention is most appropriate to include in the care plan?
- A. Instruct the client to use pursed-lip breathing
- B. Recommend a high-fat, low-carbohydrate diet
- C. Limit physical activity to prevent shortness of breath
- D. Encourage the client to drink large amounts of fluids
Correct answer: A
Rationale: The correct answer is A: Instruct the client to use pursed-lip breathing. Pursed-lip breathing helps improve ventilation and reduce shortness of breath in COPD clients. This technique involves inhaling slowly through the nose and exhaling through pursed lips. Choice B is incorrect because a high-fat, low-carbohydrate diet is not recommended for individuals with COPD as it can lead to weight gain and worsen respiratory function. Choice C is incorrect as limiting physical activity can lead to deconditioning and worsen COPD symptoms. Regular, moderate exercise is beneficial for individuals with COPD. Choice D is incorrect as excessive fluid intake can strain the heart in COPD clients. It is important to maintain adequate but not excessive fluid intake to prevent dehydration and maintain optimal lung function.
2. A 10-month-old girl is admitted with a diagnosis of possible cystic fibrosis. What question should the nurse ask the parent to assist in the diagnosis of cystic fibrosis (CF)?
- A. When you kiss her, does she taste salty?
- B. Do you notice if her urine has a musty odor?
- C. Has she been drinking cow's milk in her daily diet?
- D. How often does she have a normal bowel movement?
Correct answer: A
Rationale: The correct answer is A. Salty skin is a common sign of cystic fibrosis due to high levels of sodium in sweat. Asking about the taste of the child's skin provides valuable information related to the diagnosis of CF. Choices B, C, and D are not helpful in diagnosing cystic fibrosis. A musty odor in urine is not a typical symptom of CF. Drinking cow's milk or bowel movement frequency are not specific to CF diagnosis.
3. 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.
4. A client is admitted with acute low back pain. What action should the nurse implement to promote comfort?
- A. Ambulate with a walker for upper body support
- B. Perform abdominal curls to stretch the back muscles
- C. Position in semi-Fowler's with the knees flexed
- D. Encourage straight leg raises while lying supine
Correct answer: C
Rationale: Positioning the client in semi-Fowler's with the knees flexed is the most appropriate action to promote comfort in a client with acute low back pain. This position helps alleviate low back pain by reducing the pressure on the spine and supporting its natural curvature. Ambulating with a walker could strain the back, performing abdominal curls may exacerbate the pain, and straight leg raises while lying supine could cause further discomfort. Therefore, only positioning the client in semi-Fowler's with the knees flexed is the correct choice for promoting comfort in this scenario.
5. In Duchenne muscular dystrophy, if a child has a Gower sign, what behavior should the nurse expect the child to exhibit?
- A. Stands from sitting on the floor by using hands to walk up legs
- B. Exhibits muscular atrophy of upper and lower extremities
- C. Is unable to stand because of contractures of both hips
- D. Walks with an unsteady gait and slaps feet on the floor
Correct answer: A
Rationale: The Gower sign is a characteristic finding in Duchenne muscular dystrophy where a child uses hands to walk up the legs when standing from a sitting position due to proximal muscle weakness. This behavior is indicative of the child trying to compensate for weak hip and thigh muscles. Choices B, C, and D are incorrect because they do not describe the specific behavior associated with the Gower sign. Muscular atrophy, contractures of both hips, and an unsteady gait with foot slapping are not directly related to the Gower sign.
