Answer and Explanation

The Correct Answer is C

A. The nurse applies a tourniquet to assess a vein: Applying a tourniquet is standard practice and does not increase infection risk if proper technique is used.

B. The nurse dons gloves before starting the IV: Wearing gloves minimizes the risk of infection for both the patient and the nurse.

C. The nurse blows on the area cleansed with alcohol to dry it quickly: Blowing on the site introduces bacteria from the nurse's breath to the cleansed area, increasing the risk of infection.

D. The nurse cleans the area with an alcohol pad: Cleaning the site with alcohol reduces the risk of infection and is standard practice.

Correct Answer is C

Explanation

A. Skeletal muscle weakness: This is more commonly seen with hypercalcemia, not hypocalcemia. Hypocalcemia typically causes neuromuscular irritability, which manifests as muscle spasms rather than weakness.

B. Decreased deep-tendon reflexes: This is more commonly seen with hypercalcemia. Hypocalcemia typically increases neuromuscular irritability and can cause hyperactive reflexes.

C. Tingling of the lips: This is a classic sign of hypocalcemia, as low calcium levels can lead to neuromuscular excitability, which can cause sensations like tingling (paresthesia) around the lips and fingers.

D. Hypoactive bowel sounds: Hypocalcemia typically increases bowel motility, which can lead to hyperactive bowel sounds, not hypoactive bowel sounds.

A. Increased appetite B. Hyporeflexia C. Constipation D. Headache

Correct Answer is D

Explanation

A. Increased appetite: Hyponatremia does not typically cause increased appetite.

B. Hyporeflexia: Severe hyponatremia may lead to neurological symptoms, but reflex changes are less common.

C. Constipation: This is unrelated to sodium levels.

D. Headache: Hyponatremia causes cellular swelling, including in the brain, leading to headache, nausea, and neurological symptoms.
