HESI 799 RN Exit Exam

Correct Answer: C

Rationale: Sims' position with the right leg flexed is the most appropriate position for administering an enema to a client with severe constipation. This position helps in promoting the flow of the enema solution into the rectum and facilitates the evacuation of stool. Supine position with the head elevated 30 degrees (Choice A) is not ideal for administering an enema as it does not facilitate the flow of the solution. Left lateral position with the right leg flexed (Choice B) is not the best choice for administering an enema. Prone position with the head turned to the side (Choice D) is also not suitable for administering an enema as it does not assist in the proper administration and retention of the solution.

Correct Answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

Correct Answer: C

Rationale: A serum ammonia level of 80 mcg/dl is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. Elevated ammonia levels are associated with impaired liver function and can lead to mental status changes. Serum bilirubin (Choice A) is elevated in cirrhosis but not as concerning for acute intervention as high ammonia levels. Serum albumin (Choice B) and serum sodium (Choice D) levels are important in cirrhotic patients but are not as directly associated with hepatic encephalopathy as ammonia levels.

Correct Answer: A

Rationale: The correct answer is A: Cold sensitivity. Cold sensitivity is a common symptom of hypothyroidism, a condition that affects the thyroid gland's ability to produce enough hormones. As a postmenopausal woman presents with cold sensitivity, it may indicate an underlying thyroid issue. Hot flashes (choice B) are more commonly associated with menopause than thyroid dysfunction. While weight gain (choice C) and dry skin (choice D) can also be symptoms of thyroid disorders, cold sensitivity is more specific and indicative of hypothyroidism, requiring prompt evaluation by a healthcare provider.

Correct Answer: C

Rationale: Increasing humidity in the client's room is the initial intervention for managing thick, tenacious secretions in a client with a tracheostomy. Adequate humidity helps to hydrate secretions, making them easier to clear, thus improving airway clearance. Encouraging fluid intake (Choice A) can be beneficial but is not the first-line intervention. Administering a mucolytic agent (Choice B) may be considered if increasing humidity alone is insufficient. Performing deep suctioning (Choice D) should be reserved for when other measures like increasing humidity have been ineffective.
