When another nurse enters the room in response to a call, after checking the client's pulse and respirations during CPR on an adult in cardiopulmonary arrest, what should be the function of the second nurse?

A. Relieve the nurse performing CPR

B. Go get the code cart

C. Participate with the compressions or breathing

D. Validate the client's advanced directive

Correct Answer: C
Rationale: The correct answer is to participate in compressions or breathing. This is essential to ensure continuous and effective CPR. Relieving the nurse performing CPR (Choice A) is not recommended as it can interrupt the life-saving procedure. Going to get the code cart (Choice B) may be necessary in certain situations but should not take precedence over providing immediate assistance in CPR. Validating the client's advanced directive (Choice D) is not the primary role in this scenario where urgent action is needed to support the client's circulation and breathing.

A nurse is reinforcing teaching about food choice with the mother of an 8-month-old infant. Which of the following statements by the mother indicates a need for further teaching?

• A. I will give my child peanut butter and mashed egg whites.
• B. I will give my child rice cereal and crackers.
• C. I will give my child pureed liver and strained pears.
• D. I will give my child applesauce and green peas.

Correct Answer: A
Rationale: The correct answer is A because peanut butter and egg whites are not recommended for infants under 12 months due to the risk of choking and allergies. Choices B, C, and D are appropriate food choices for an 8-month-old infant. Rice cereal, crackers, pureed liver, strained pears, applesauce, and green peas are all suitable options for introducing solid foods to infants.

Which of these nursing assessments would be the highest priority for a client at risk for aspiration pneumonia?

• A. Assessing the client's level of consciousness
• B. Monitoring the client's oxygen saturation
• C. Checking the client's gag reflex before eating or drinking
• D. Monitoring the client's intake and output

Correct Answer: C
Rationale: Checking the client's gag reflex before eating or drinking is the highest priority for a client at risk for aspiration pneumonia. Aspiration pneumonia can occur when food, liquids, or saliva are inhaled into the lungs, leading to inflammation or infection. Checking the gag reflex helps prevent the aspiration of substances into the lungs. Assessing the client's level of consciousness (Choice A) is important but not as immediately critical as checking the gag reflex. Monitoring oxygen saturation (Choice B) is essential for respiratory assessment but does not directly prevent aspiration. Monitoring intake and output (Choice D) is important for overall client management but does not specifically address the risk of aspiration pneumonia.

In a client with chronic kidney disease having a serum potassium level of 6.5 mEq/L, which assessment is the most critical for the nurse to perform?

• A. Neurological status
• B. Cardiac status
• C. Respiratory status
• D. Gastrointestinal status

Correct Answer: B
Rationale: Corrected Rationale: Assessing cardiac status is crucial in hyperkalemia as high potassium levels can result in life-threatening arrhythmias. Monitoring the heart rhythm and ECG findings is essential to prevent cardiac complications. Neurological status, respiratory status, and gastrointestinal status are important assessments too, but in the context of hyperkalemia, cardiac status takes precedence due to the immediate risk of cardiac arrhythmias.

After a client has an enteral feeding tube inserted, the most accurate method for verification of placement is

• A. Abdominal x-ray
• B. Auscultation
• C. Flushing tube with saline
• D. Aspiration for gastric contents

Correct Answer: D
Rationale: After the insertion of an enteral feeding tube, the most accurate method for verifying its placement is by aspirating gastric contents. This method ensures that the tube is correctly positioned in the stomach. Abdominal x-ray can provide additional confirmation but is not as immediate or practical. Auscultation and flushing the tube with saline are not as reliable as aspirating gastric contents for verifying proper placement of an enteral feeding tube.
