HESI RN CAT Exit Exam

Correct Answer: C

Rationale: When a nurse observes periods of apnea in a client experiencing Cheyne-Stokes respirations, measuring the length of the apneic periods is essential. This action helps in determining the severity of Cheyne-Stokes respirations by providing valuable information about the duration of interrupted breathing cycles. Elevating the head of the client's bed (Choice A) may be beneficial in some respiratory conditions but is not the priority in Cheyne-Stokes respirations. Auscultating the client's breath sounds (Choice B) is a general assessment and may not directly address the issue of apnea in Cheyne-Stokes respirations. Suctioning the client's oropharynx (Choice D) is not the initial intervention for managing Cheyne-Stokes respirations unless secretions are obstructing the airway.

Correct Answer: B

Rationale: To ensure the effectiveness of the antibiotic and manage blood glucose levels, the client should take the Zithromax two hours after eating. Option A is incorrect because obtaining a new breakfast tray is not necessary to administer the missed dose. Option C is incorrect as skipping a dose can lead to decreased effectiveness of the antibiotic. Option D is incorrect because providing an antacid is not indicated in this situation.

Correct Answer: B

Rationale: The correct instruction is to advise the client to avoid alcohol while taking phenytoin. Alcohol can interact with phenytoin, making it less effective and leading to increased side effects. Taking the medication with meals (Choice A) may help reduce gastrointestinal upset but is not the most crucial instruction for this medication. Limiting sodium intake (Choice C) is not directly related to phenytoin therapy. Taking the medication at bedtime (Choice D) is not a standard instruction for phenytoin administration.

Correct Answer: C

Rationale: The correct answer is to implement seizure precautions. Phenytoin is an antiepileptic medication used for seizure control. Seizure precautions are crucial for clients taking this medication to ensure their safety during a seizure episode. Monitoring serum calcium levels (Choice A) is not directly related to phenytoin therapy. Obtaining a baseline electrocardiogram (Choice B) is important for some medications but not the priority for a client on phenytoin. Encouraging a low-protein diet (Choice D) is not specifically indicated for clients on phenytoin and is not the most important intervention.

Correct Answer: D

Rationale: Combining legumes and grains ensures the client receives all essential amino acids to form complete proteins, which is crucial in a vegetarian diet. Options A, B, and C are incorrect. Option A is not necessary as there are plant-based sources of essential amino acids in a lacto-vegetarian diet. Option B suggests vitamin K, which is not directly related to enhancing red blood cell production. Option C mentions increasing dark yellow vegetables, which are sources of non-heme iron, but combining legumes and grains is more effective in addressing the protein needs of a lacto-vegetarian.
