HESI RN CAT Exit Exam

Correct Answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

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: A

Rationale: The highest priority nursing intervention for a laboring client following administration of regional anesthesia is to ensure safety by raising the side rails and placing the call bell within reach. This is crucial to prevent falls and to ensure that the client can call for assistance if needed. Teaching the client how to push effectively (Choice B) is important but not the highest priority at this moment. Timing and recording uterine contractions (Choice C) are essential but not as immediate as ensuring safety post-anesthesia. Positioning the client for proper distribution of anesthesia (Choice D) is important but ensuring immediate safety takes precedence in this situation.

Correct Answer: B

Rationale: The correct answer is to instill the first dose of nystatin vaginally per applicator. Nystatin is an antifungal medication used to treat yeast infections, which are characterized by 'cottage cheese' discharge. Cleansing the perineum with warm soapy water may help with hygiene but does not address the underlying infection. Performing a glucose measurement is not relevant to the diagnosis of a vaginal infection. Obtaining a blood specimen for STDs is not the priority in this scenario as the symptoms described are indicative of a yeast infection.

Correct Answer: D

Rationale: The correct instruction for an elderly client taking both an ACE inhibitor and a calcium channel blocker is to change positions slowly. Both medications can lead to orthostatic hypotension, a sudden drop in blood pressure when changing positions, which can increase the risk of falls. Instructing the client to change positions slowly helps prevent falls. Wearing long-sleeved clothing when outdoors does not directly relate to the medication combination. Reporting the onset of a sore throat is important for monitoring potential side effects but is not specific to these medications. While potassium levels should be monitored with ACE inhibitors, eating plenty of potassium-rich foods without guidance can lead to hyperkalemia, a potential side effect of ACE inhibitors.
