Nursing Elites

1. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Increased serum hemoglobin levels
• D. Decreased serum potassium levels

Correct answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.

2. A client with acute hemorrhagic anemia is to receive four units of packed RBCs (red blood cells) as rapidly as possible. Which intervention is most important for the LPN/LVN to implement?

• A. Obtain the pre-transfusion hemoglobin level.
• B. Prime the tubing and set up the blood pump.
• C. Monitor vital signs every 15 minutes for the first hour.
• D. Ensure the accuracy of the blood type match.

Correct answer: D

Rationale: Ensuring the accuracy of the blood type match is crucial to prevent transfusion reactions. The LPN/LVN must prioritize this step to avoid adverse outcomes. Obtaining the pre-transfusion hemoglobin level (Option A) is important but not as critical as ensuring blood type compatibility. Priming the tubing and setting up the blood pump (Option B) and monitoring vital signs every 15 minutes (Option C) are essential steps in the transfusion process, but the primary concern should be preventing transfusion reactions by verifying blood type compatibility.

3. The nurse is preparing to administer digoxin (Lanoxin) to a client with heart failure. Which assessment finding would prompt the nurse to withhold the medication and contact the healthcare provider?

• A. Heart rate of 55 beats per minute
• B. Blood pressure of 140/90 mmHg
• C. Respiratory rate of 20 breaths per minute
• D. Blood glucose level of 150 mg/dL

Correct answer: A

Rationale: A heart rate below 60 beats per minute is a contraindication for administering digoxin, as it can lead to bradycardia. Bradycardia is a common adverse effect associated with digoxin toxicity. Blood pressure of 140/90 mmHg, respiratory rate of 20 breaths per minute, and blood glucose level of 150 mg/dL are within normal limits and would not warrant withholding the medication or contacting the healthcare provider in this context. Therefore, a heart rate of 55 beats per minute would prompt the nurse to withhold digoxin and notify the healthcare provider.

4. A client with a tracheostomy is being taught by a nurse and their family how to care for the tracheostomy at home. Which of the following should the nurse include in the teaching?

• A. Use tracheostomy covers when outdoors.
• B. Clean the tracheostomy with alcohol.
• C. Replace the tracheostomy tube every week.
• D. Cover the tracheostomy with a wet cloth when sleeping.

Correct answer: A

Rationale: Using tracheostomy covers when outdoors is essential to protect the tracheostomy from dust and debris, reducing the risk of infection. Tracheostomy covers help maintain cleanliness and prevent foreign particles from entering the stoma. Choice B is incorrect because cleaning the tracheostomy with alcohol can be too harsh and drying for the skin surrounding the stoma, leading to skin irritation. Choice C is incorrect as tracheostomy tubes are typically replaced only when clinically indicated or as per the healthcare provider's instructions, not routinely every week, to prevent unnecessary risks and complications. Choice D is incorrect as covering the tracheostomy with a wet cloth when sleeping can create a moist environment ideal for bacterial growth, increasing the risk of infection and skin breakdown. It is important to keep the tracheostomy site clean, dry, and protected to maintain optimal hygiene and prevent complications.

5. A client with diabetes mellitus is learning to self-administer insulin. Which action by the client indicates the need for further teaching?

• A. The client rotates injection sites on the abdomen.
• B. The client draws up the insulin dose after warming the vial to room temperature.
• C. The client pinches the skin before injecting the insulin.
• D. The client injects the insulin at a 90-degree angle.

Correct answer: B

Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.
