Nursing Elites

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

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct answer: D

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.

2. The LPN is checking for residual before administering enteral feeding through a PEG tube. Which of these steps is incorrect?

• A. The LPN elevates the head of the bed by at least 30 degrees.
• B. If the residual is greater than 200mL, the LPN should not administer the enteral feeding.
• C. The LPN should discard the residual before administering the tube feeding.
• D. The residual pH level is tested to ensure appropriate placement.

Correct answer: C

Rationale: The incorrect step is choice C. The residual should be discarded before administering the tube feeding. Discarding the residual is essential to prevent contamination and ensure accurate measurement of the enteral feeding. Elevating the head of the bed by at least 30 degrees (choice A) is correct as it helps prevent aspiration during feeding. Testing the pH level of the residual (choice D) ensures proper placement of the tube. Withholding feeding if the residual is greater than 200mL (choice B) is crucial to prevent overfeeding, making this statement correct.

3. What is a true statement about post-discharge follow-up?

• A. The nurse should ensure the client is educated on their discharge instructions.
• B. If the client seems stable, they likely do not need a follow-up visit.
• C. The physician is responsible for ensuring the client has their prescriptions upon discharge.
• D. If the client has questions, the nurse should address them before discharge.

Correct answer: A

Rationale: The correct statement is that the nurse should ensure the client is educated on their discharge instructions. This is crucial to promote continuity of care and prevent adverse events. The responsibility of educating the client falls on the nurse, not assuming stability without a follow-up visit. While the physician may prescribe medications, it is the nurse's responsibility to ensure the client has them before discharge. Instructing the client to bring up questions at a follow-up appointment is not ideal; all questions should be addressed before discharge to ensure the client's understanding and compliance.

4. Which of the following statements by a client with gastroesophageal reflux disease (GERD) indicates adequate understanding?

• A. "I should eat right before bedtime."?
• B. "I should eat large meals."?
• C. "I should sit up after eating."?
• D. "I should lie flat after eating."?

Correct answer: C

Rationale: The correct statement for a client with GERD is, 'I should sit up after eating.' This helps prevent reflux by keeping the stomach contents down. Choice A is incorrect as eating right before bedtime can exacerbate GERD symptoms by increasing the likelihood of reflux during the night. Choice B is incorrect because consuming large meals can lead to increased stomach pressure and worsen reflux symptoms. Choice D is incorrect because lying flat after eating can promote reflux due to gravity assisting the flow of stomach contents into the esophagus, worsening GERD.

5. A safety measure to implement when transferring a client with hemiparesis from a bed to a wheelchair is:

• A. standing the client and walking him or her to the wheelchair.
• B. moving the wheelchair close to the client's bed and standing and pivoting the client on his unaffected extremity to the wheelchair.
• C. moving the wheelchair close to the client's bed and standing and pivoting the client on his affected extremity to the wheelchair.
• D. having the client stand and push his body to the wheelchair.

Correct answer: B

Rationale: When transferring a client with hemiparesis from a bed to a wheelchair, it is crucial to ensure their safety. The correct safety measure involves moving the wheelchair close to the client's bed and having the client stand and pivot on his unaffected extremity to the wheelchair. This method provides support with the unaffected limb, reducing the risk of falls and promoting a safer transfer. Choice A is incorrect because walking the client is unsafe and not recommended. Choice C is incorrect as pivoting the client on his affected extremity can lead to injury or falls due to weakness or lack of control. Choice D is incorrect as it puts the client at risk by requiring them to push their body, which may not be feasible or safe for someone with hemiparesis.
