A nurse is preparing to change the bed linens of a client who has AIDS and is incontinent of stool. Which of the following personal protective equipment (PPE) should the nurse don prior to providing client care? (Select all that apply.)

Choice A reason: This is an incorrect action, because instructing the client to blink several times after instillation of the medication can cause the medication to drain out of the eye and reduce its effectiveness.

Choice B reason: This is a correct action, but not the best one. Asking the client to look straight ahead during instillation of the medication can help the nurse to aim the drop accurately and avoid touching the eye with the dropper.

Choice C reason: This is the best action, because applying pressure to the bridge of the nose after instillation of the medication can prevent the medication from entering the systemic circulation and causing adverse effects, such as bradycardia, hypotension, or bronchospasm.

Choice D reason: This is an incorrect action, because placing each drop of the medication directly on to the client's cornea can cause irritation, injury, or infection to the eye. The medication should be placed in the lower conjunctival sac of the eye.

Choice A reason: This is an incorrect finding, because elevated blood pressure is not a sign of hypoparathyroidism, which is a condition that occurs when the parathyroid glands produce insufficient parathyroid hormone (PTH). PTH regulates the calcium and phosphorus levels in the blood and bones. Elevated blood pressure can be a sign of hyperparathyroidism, which is the opposite condition.

Choice B reason: This is the correct finding, because involuntary muscle spasms are a sign of hypoparathyroidism, which causes hypocalcemia, or low blood calcium levels. Hypocalcemia can cause neuromuscular irritability and tetany, which are manifested by muscle spasms, twitching, cramps, or seizures.

Choice C reason: This is an incorrect finding, because cold intolerance is not a sign of hypoparathyroidism, but a sign of hypothyroidism, which is a condition that occurs when the thyroid gland produces insufficient thyroid hormone. Thyroid hormone regulates the metabolism and body temperature. Cold intolerance can also be a sign of Hashimoto's thyroiditis, which is an autoimmune disease that causes inflammation and destruction of the thyroid gland.

Choice D reason: This is an incorrect finding, because weight loss is not a sign of hypoparathyroidism, but a sign of hyperthyroidism, which is a condition that occurs when the thyroid gland produces excessive thyroid hormone. Thyroid hormone increases the metabolism and energy expenditure. Weight loss can also be a sign of Graves' disease, which is an autoimmune disease that causes overstimulation and enlargement of the thyroid gland.
