Fundamentals of Nursing Vital Signs Practice Questions Questions
Question 1 of 5
A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which laboratory value should the nurse monitor most closely?
Correct Answer: B
Rationale: Insulin in DKA shifts potassium into cells, risking hypokalemia; thus, serum potassium (B) is monitored closely. Sodium (A) and BUN (C) are less urgent, and A1c (D) reflects long-term control.
Question 2 of 5
Which action for correction does the nurse expect to occur in the client who has a pH of 7.49?
Correct Answer: C
Rationale: A pH of 7.49 indicates alkalosis. The kidneys compensate by excreting H+ ions to lower pH. Reabsorbing bicarbonate (A) would worsen alkalosis. Increased respiratory rate (B) would increase CO2 loss worsening alkalosis. Decreased CO2 excretion (D) is a respiratory compensation not renal.
Question 3 of 5
Which action may the nurse safely delegate to an assistive personnel (AP) when caring for a client who has urinary incontinence?
Correct Answer: D
Rationale: Assisting to the bathroom (D) is within AP scope. Instructing (A) assessing skin (B) and monitoring electrolytes (C) require nursing judgment.
Question 4 of 5
The nurse wants to screen the patient for cervical cancer
Correct Answer: D
Rationale: The lithotomy position is used for cervical cancer screening (e.g. Pap smear) as it provides optimal access to the cervix. Fowler's (A) is for respiratory or feeding support side-lying (B) is for comfort and prone (C) is for posterior access.
Question 5 of 5
If you are looking for trends in a patient's vital signs
Correct Answer: B
Rationale: The TPR (temperature pulse respiration) chart tracks vital sign trends over time. Admission sheet (A) and assessment (C) provide baseline data and activity flow sheet (D) tracks activities not vital signs.
