A nurse is monitoring a client who was admitted for hypocalcemia. Which of the following findings should the nurse expect?
Positive Chvostek's sign
Hypotension
Confusion
Positive Babinski reflex
The Correct Answer is A
A. Positive Chvostek's sign. Hypocalcemia increases neuromuscular excitability, leading to involuntary twitching of facial muscles when the facial nerve is tapped. This sign is a well-known indicator of calcium deficiency and reflects heightened nerve sensitivity.
B. Hypotension. While severe hypocalcemia can affect cardiovascular function, hypotension is not a primary or consistent finding. More commonly, calcium imbalances affect muscle contractions rather than directly causing low blood pressure.
C. Confusion. Hypocalcemia can cause neurological symptoms, but confusion is more common in severe or prolonged cases. Early manifestations are usually neuromuscular, such as tetany or muscle cramps, rather than cognitive impairment.
D. Positive Babinski reflex. This reflex is associated with upper motor neuron dysfunction and neurological disorders rather than electrolyte imbalances like hypocalcemia. Calcium deficiency primarily affects peripheral nerves and muscle excitability.

Correct Answer is A
Explanation
A. "I am thankful I am done having children." This statement indicates that the client understands a key consequence of a hysterectomy—permanent infertility. Understanding the implications of the procedure is an essential component of informed consent, demonstrating that the client has received and comprehended relevant information.
B. "I will have a large scar on my stomach after this procedure." A vaginal hysterectomy is performed through the vaginal canal, meaning there will be no abdominal incision or visible scar. This statement reflects a misunderstanding of the surgical approach, indicating that the client may not have fully understood the procedure.
C. "I should expect my periods to resume in 1 month." A hysterectomy involves the removal of the uterus, which results in the permanent cessation of menstruation. This statement suggests that the client does not fully understand the effects of the procedure, which is inconsistent with informed consent.
D. "I will no longer need a regular gynecological examination." Even after a hysterectomy, regular gynecological exams remain important, especially if the cervix or ovaries are retained. These exams help monitor overall reproductive health and screen for conditions such as ovarian cancer or vaginal atrophy. This statement indicates misinformation about postoperative care.
Correct Answer is A
Explanation
A. Inject 15 units of air into the regular insulin vial. When mixing NPH and regular insulin, air is first injected into both vials without touching the solution. After injecting air into the NPH vial, the next step is to inject air into the regular insulin vial to maintain proper vial pressure before withdrawing the dose.
B. Place the cap over the needle. Recapping needles increases the risk of needlestick injuries and is not necessary during the insulin preparation process. The needle should remain uncapped until both insulins are drawn and the injection is ready.
C. Withdraw 10 units of NPH insulin. Regular insulin should be drawn first to prevent contamination with NPH insulin. Since NPH is a cloudy suspension and regular insulin is clear, drawing regular insulin first ensures that the short-acting insulin remains unaltered.
D. Verify the dosage with another nurse. While verifying high-risk medications like insulin is important, the appropriate step after injecting air into the NPH vial is to proceed with injecting air into the regular insulin vial before withdrawing any insulin.
