A nurse is teaching a client who is pregnant about nonstress testing. Which of the following statements by the client indicates an understanding of the teaching?
"During this test, I must not eat or drink anything."
"During this test, I will push a button if my baby moves."
"I will get oxytocin during this test."
"This test will tell me if my baby has a genetic problem."
The Correct Answer is B
A. "During this test, I must not eat or drink anything." – Incorrect. There are no dietary restrictions before a nonstress test (NST). In fact, eating may stimulate fetal movement.
B. "During this test, I will push a button if my baby moves." – Correct. The client is asked to press a button when fetal movement is felt to correlate with fetal heart rate accelerations.
C. "I will get oxytocin during this test." – Incorrect. Oxytocin is used in a contraction stress test (CST), not an NST.
D. "This test will tell me if my baby has a genetic problem." – Incorrect. The NST evaluates fetal well-being and oxygenation, not genetic conditions.

Correct Answer is B
Explanation
A. Insulin vials should not be shaken because this can create air bubbles, leading to inaccurate dosing. Instead, NPH insulin should be gently rolled between the palms to evenly mix the suspension. Regular insulin does not require mixing.
B. Once regular and NPH insulin are mixed, they should be administered promptly to maintain their stability and effectiveness. Delaying administration may alter insulin absorption, leading to unpredictable glucose control.
C. Regular insulin should be drawn up before NPH insulin to prevent contaminating the clear regular insulin with the cloudy NPH insulin. The correct order is to inject air into the NPH vial first (without withdrawing insulin), then inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
D. The correct technique is to first inject air into the NPH vial, then inject air into the regular insulin vial. This prevents contamination and maintains sterility. However, when withdrawing insulin, regular insulin is drawn first to prevent mixing of NPH insulin into the regular insulin vial.
Correct Answer is A
Explanation
A. Muscle twitching – Hypocalcemia (normal range: 8.5–10.5 mg/dL) causes neuromuscular excitability, leading to muscle twitching, tetany, and positive Chvostek's and Trousseau's signs.
B. Hypertension – Hypocalcemia does not cause hypertension; instead, it may lead to hypotension.
C. Bounding pulse – Hypocalcemia does not cause a bounding pulse; it may cause weak and irregular pulses.
D. Hypoactive bowel sounds – Hypocalcemia is more likely to cause hyperactive bowel sounds and diarrhea rather than hypoactive bowel sounds.
