Nursing Elites

1. While auscultating the anterior chest of a newly admitted patient, what would the nurse expect to hear?

• A. Normal breathing sounds
• B. Wheezing
• C. Crackles
• D. Stridor

Correct answer: A

Rationale: When auscultating the chest, normal breathing sounds are expected in a healthy individual. Wheezing is a high-pitched whistling sound that indicates narrowed airways and is often heard in conditions like asthma. Crackles are fine, crackling sounds heard on inspiration or expiration and are associated with conditions like pneumonia or heart failure. Stridor is a high-pitched, harsh sound heard during inspiration due to upper airway obstruction. Therefore, choices B, C, and D indicate abnormal respiratory findings, while choice A signifies normal breathing sounds.

2. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?

• A. Decreased calcium
• B. Elevated potassium
• C. Increased sodium
• D. Low hemoglobin

Correct answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.

3. During the check-up of a 2-month-old infant at a well-baby clinic, the mother expresses concern to the nurse because a flat pink birthmark on the baby's forehead and eyelid has not gone away. What is an appropriate response by the nurse?

• A. Mongolian spots are a normal finding in dark-skinned infants.
• B. Port wine stains are typically associated with other malformations.
• C. Telangiectatic nevi are normal and will disappear as the baby grows.
• D. The child is too young for surgical removal of these at this time.

Correct answer: C

Rationale: The correct answer is C. Telangiectatic nevi, often referred to as 'stork bites,' are common birthmarks in infants and are considered normal. These birthmarks usually fade and disappear as the child grows older. Choices A, B, and D are incorrect because Mongolian spots are bluish-gray birthmarks commonly found in darker-skinned infants, port wine stains are vascular birthmarks that typically do not disappear, and surgical removal is not recommended for telangiectatic nevi as they usually resolve on their own.

4. What is the most important action for the LPN/LVN to take to prevent infection in a client with an indwelling urinary catheter?

• A. Ensure the catheter tubing is free of kinks.
• B. Change the catheter every 72 hours.
• C. Clean the perineal area with an antiseptic solution daily.
• D. Irrigate the catheter with normal saline every shift.

Correct answer: A

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This step helps prevent obstruction in the tubing, maintaining proper urine flow and reducing the risk of infection. Changing the catheter every 72 hours is not recommended unless clinically indicated, as routine changes can increase the risk of introducing pathogens. Cleaning the perineal area with an antiseptic solution is essential for general hygiene but does not directly prevent catheter-related infections. Irrigating the catheter with normal saline every shift is not a standard practice and can introduce microorganisms into the urinary tract, increasing the risk of infection.

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.
