NCLEX PN Exam Cram

1. The PN is caring for a client with diabetes insipidus. The nurse can expect the lab work to show:

Correct answer: decreased urine osmolarity and elevated serum osmolarity.

Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.

2. What is the term for the tendency of a drug to combine with its receptor?

Correct answer: affinity

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

3. When placing a Foley catheter in a female client, what is the correct order of steps?

Correct answer: E, A, F, B, C, G, D

Rationale: The correct order for placing a Foley catheter in a female client is as follows: E. Place the client in a supine position with flexed knees, A. Prepare the sterile field, F. Place lubricant on the catheter, B. Separate labia with the non-dominant hand, C. Clean the urinary meatus using cleansing solutions and forceps, G. Place the catheter in the meatus with the dominant (sterile) hand, and D. Inflate the catheter balloon. This sequence ensures proper hygiene, patient comfort, and reduces the risk of infection. Incorrect sequences could compromise sterility, cause discomfort, and increase the risk of infection. Therefore, the correct answer is E, A, F, B, C, G, D.

4. Following a classic cholecystectomy resection for multiple stones, the PACU nurse observes serosanguinous drainage on the dressing. The most appropriate intervention is to:

Correct answer: reinforce the dressing.

Rationale: Serosanguinous drainage is expected after a classic cholecystectomy resection. The appropriate intervention is to reinforce the dressing to maintain pressure and promote clot formation. Changing the dressing prematurely increases the risk of infection as it disturbs the wound. Applying an abdominal binder is not indicated as it can interfere with visualizing the dressing and assessing for any signs of bleeding or infection. Notifying the physician is not necessary at this point unless there are signs of excessive bleeding or other concerning symptoms.

5. When planning care for a client taking Heparin, which nursing diagnosis should the nurse address first?

Correct answer: Risk for injury related to active loss of blood from the vascular space

Rationale: The correct answer is 'Risk for injury related to active loss of blood from the vascular space.' When a client is taking Heparin, the primary concern is the risk of bleeding due to its anticoagulant properties. Monitoring for signs of active blood loss is crucial to prevent complications like hemorrhage. While ineffective tissue perfusion, deficient knowledge, and impaired skin integrity are important, they are secondary to the immediate risk of bleeding in clients taking anticoagulants like Heparin.
