The nurse is preparing to administer Regular insulin to a client with a blood glucose of 265. What action should the nurse take to determine the correct dose?

Review the patient’s previous blood glucose levels

No review is necessary before administering insulin

Review the Regular insulin sliding scale for administration in the patient’s electronic medical record

Review the patient’s previous insulin administration doses

Answer and Explanation

The Correct Answer is C

Choice A reason: This is incorrect. Reviewing the patient’s previous blood glucose levels may not be helpful in determining the correct dose of insulin, as the blood glucose level can fluctuate depending on various factors, such as food intake, activity, stress, and illness. The previous blood glucose levels may not reflect the current insulin needs of the patient¹.

Choice B reason: This is incorrect. No review is not an option before administering insulin, as insulin is a highalert medication that can cause serious harm if given incorrectly. The nurse should always check the patient’s blood glucose level, the insulin order, the insulin type, the insulin dose, the insulin expiration date, and the insulin injection site before giving insulin.

Choice C reason: This is correct. Reviewing the Regular insulin sliding scale for administration in the patient’s electronic medical record is the best action to determine the correct dose of insulin. A sliding scale is a chart of insulin dosages based on blood glucose level and mealtime. It is used to adjust the insulin dose according to the patient’s blood glucose level and insulin sensitivity. The nurse should follow the sliding scale protocol and verify the insulin dose with another nurse before administering it.

Choice D reason: This is incorrect. Reviewing the patient’s previous insulin administration doses may not be helpful in determining the correct dose of insulin, as the insulin dose may vary depending on the patient’s blood glucose level and insulin sensitivity. The previous insulin doses may not reflect the current insulin needs of the patient¹.

Correct Answer is A

Explanation

Choice A reason: This is correct. Excedrin contains a combination of aspirin, acetaminophen, and caffeine. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that reduces pain, inflammation, and swelling. Acetaminophen is a pain reliever and a fever reducer. Caffeine is a central nervous system stimulant that enhances the pain-relieving function of aspirin and acetaminophen.

Choice B reason: This is incorrect. Ibuprofen and naproxen are both NSAIDs, but they are not the same as aspirin. They have different chemical structures and may have different effects and side effects. Caffeine is not an ingredient in ibuprofen or naproxen products.

Choice C reason: This is incorrect. Loratadine is an antihistamine that is used to treat allergies, not headaches. It does not have any pain-relieving or anti-inflammatory properties. Caffeine is not an ingredient in loratadine products.

Choice D reason: This is incorrect. Naproxen is an NSAID, but it is not the same as aspirin. It has a different chemical structure and may have different effects and side effects. Loratadine is an antihistamine that is used to treat allergies, not headaches. It does not have any pain-relieving or anti-inflammatory properties. Caffeine is not an ingredient in acetaminophen, naproxen, or loratadine products.

A. Miosis B. Sedation C. Respiratory depression D. Euphoria

Correct Answer is C

Explanation

Choice A reason: This is incorrect. Miosis is the constriction of the pupils, which can also be caused by morphine, but it is not a life-threatening side effect. Miosis occurs because morphine stimulates the parasympathetic nervous system, which controls the muscles that constrict the pupils¹.

Choice B reason: This is incorrect. Sedation is the state of being calm, relaxed, and sleepy, which can also be caused by morphine, but it is not a life-threatening side effect. Sedation occurs because morphine depresses the central nervous system, which reduces the activity of the brain and the body.

Choice C reason: This is correct. Respiratory depression is the slowing down of breathing, which can be a life-threatening side effect of morphine. Respiratory depression occurs because morphine depresses the respiratory center in the brainstem, which regulates the rate and depth of breathing. If the breathing becomes too slow or shallow, the patient may not get enough oxygen and may lose consciousness or die.

Choice D reason: This is incorrect. Euphoria is the feeling of intense happiness, pleasure, or wellbeing, which can also be caused by morphine, but it is not a life-threatening side effect. Euphoria occurs because morphine stimulates the reward system in the brain, which releases dopamine, a neurotransmitter that causes positive emotions.
