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.

A healthcare professional is teaching about home safety with a client. Which of the following instructions should the healthcare professional include?
- A. Unplug electronics by holding the plug
- B. Use electrical tape to secure extension cords next to baseboards on the floor
- C. To use a fire extinguisher, aim at the base of the flames
- D. Install slip-resistant rugs on tile floors
Correct Answer: B
Rationale: The correct answer is to use electrical tape to secure extension cords next to baseboards on the floor. This practice helps prevent tripping and electrical hazards by keeping cords out of the way. Option A is incorrect as unplugging electronics should be done by holding the plug, not the cord itself. Option C is incorrect because when using a fire extinguisher, it should be aimed at the base of the flames, not at the top. Option D is not directly related to home safety teaching and may not be necessary for all clients, as it suggests an unnecessary change that may not improve safety.
When caring for an older adult client who becomes agitated when asked to remove dentures before surgery, which of the following responses should the nurse make?
- A. "What worries you about being without your teeth?"
- B. "You need to follow the preoperative instructions and remove your dentures."
- C. "It's important to remove dentures to ensure proper fitting of the mask during anesthesia."
- D. "I will explain why dentures need to be removed before surgery."
Correct Answer: A
Rationale: The correct response is to ask the client about their concerns regarding being without their teeth. This approach helps address the client's anxiety and provides insight into the reason for their agitation. Choice B is authoritarian and does not address the client's emotional needs. Choice C focuses on the technical aspect of surgery and does not address the client's emotional state. Choice D implies a one-way communication without addressing the client's feelings or concerns.
A nurse on a med-surg unit is teaching a newly licensed nurse about tasks to delegate to APs. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?
- A. An AP may take orthostatic blood pressure measurements from a client who reports dizziness.
- B. An AP may monitor the peripheral IV insertion site of a client who is receiving replacement fluids.
- C. An AP may perform a central line dressing change for a client who is ready for discharge.
- D. An AP may ambulate a client who had a stroke 2 days ago.
Correct Answer: D
Rationale: The correct answer is D. Delegating the task of ambulating a client who had a stroke 2 days ago to an AP is appropriate. This task falls within the scope of practice for an AP and can help promote mobility and prevent complications. Choices A, B, and C involve more complex nursing assessments or procedures that require a higher level of training and expertise. Taking orthostatic blood pressure measurements, monitoring a peripheral IV insertion site, and performing a central line dressing change should be tasks performed by licensed nurses to ensure proper assessment and management of the client's condition.
A healthcare professional is planning to obtain the vital signs of a 2-year-old child who is experiencing diarrhea and who might have a right ear infection. Which of the following routes should the healthcare professional use to obtain the temperature?
- A. Temporal
- B. Oral
- C. Rectal
- D. Axillary
Correct Answer: C
Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.
During a peripheral vascular assessment, a healthcare professional places the bell of the stethoscope on a client's neck and hears an audible vascular sound associated with turbulent blood flow. This sound indicates which of the following?
- A. Narrowed arterial lumen
- B. Distended jugular veins
- C. Impaired ventricular contraction
- D. Asynchronous closure of the aortic and pulmonic valve
Correct Answer: A
Rationale: The correct answer is A: Narrowed arterial lumen. Arterial bruits are abnormal sounds caused by turbulent blood flow through narrowed or occluded arteries. This turbulent flow creates a blowing sound, which is heard as an arterial bruit. Distended jugular veins (choice B) are typically associated with venous issues, not arterial abnormalities. Impaired ventricular contraction (choice C) and asynchronous closure of the aortic and pulmonic valve (choice D) are not directly related to the audible vascular sound described in the scenario.
