A nurse is reviewing the laboratory results of a client who has hypothyroidism. The client's calcium level is 7.6 mg/dL. When assessing the client, which of the following findings should the nurse expect?

Muscle twitching

Hypertension

Bounding pulse

Hypoactive bowel sounds

Answer and Explanation

The Correct Answer is A

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.

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.

A. Influenza B. Hepatitis A C. Varicella D. Rotavirus

Correct Answer is D

Explanation

A. Influenza – The first dose of the influenza vaccine is recommended at 6 months, not 2 months.

B. Hepatitis A – Hepatitis A vaccine is typically given at 12-23 months, not at 2 months.

C. Varicella – The varicella (chickenpox) vaccine is given at 12-15 months, so it is not appropriate for a 2-month-old.

D. Rotavirus – This is the correct answer. The rotavirus vaccine is recommended at 2 months, 4 months, and possibly 6 months, depending on the vaccine brand used.
