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
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 D
Explanation
Choice A reason: This is incorrect. Aspirin can be used to relieve headache, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice B reason: This is incorrect. Aspirin can be used to reduce fever, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice C reason: This is incorrect. Aspirin does not act as an antiviral. It has no effect on viral infections. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice D reason: This is correct. Aspirin prevents further clot formation by inhibiting the activity of platelets, which are blood cells that help form clots. Clots can block the blood flow to the heart and cause a heart attack. Aspirin reduces the chance of this happening by making the blood less sticky.
Correct Answer is D
Explanation
Choice A reason: The initial phase of drug distribution is not the correct definition of the term 'first pass effect'. Drug distribution is the process by which a drug moves from the bloodstream to the tissues and organs of the body. The initial phase of drug distribution is influenced by factors such as blood flow, tissue permeability, plasma protein binding, and tissue binding. The first pass effect is not related to drug distribution, but to drug metabolism, which is the chemical transformation of a drug in the body.
Choice B reason: The rapid absorption of a drug in the intestine is not the correct definition of the term 'first pass effect'. Drug absorption is the process by which a drug enters the bloodstream from the site of administration. The rapid absorption of a drug in the intestine depends on factors such as the drug formulation, the pH of the gastrointestinal tract, the presence of food or other drugs, and the surface area and motility of the intestine. The first pass effect is not related to drug absorption, but to drug metabolism, which is the chemical transformation of a drug in the body.
Choice C reason: The initial rapid excretion of a drug through the urinary system is not the correct definition of the term 'first pass effect'. Drug excretion is the process by which a drug or its metabolites are eliminated from the body. The initial rapid excretion of a drug through the urinary system is influenced by factors such as the renal blood flow, the glomerular filtration rate, the tubular secretion and reabsorption, and the urine pH. The first pass effect is not related to drug excretion, but to drug metabolism, which is the chemical transformation of a drug in the body.
Choice D reason: The metabolism of a drug before it reaches the systemic circulation is the correct definition of the term 'first pass effect'. Drug metabolism is the process by which a drug is chemically transformed in the body, usually by enzymes in the liver or other tissues. The first pass effect is a phenomenon of drug metabolism that occurs when a drug is administered orally and passes through the gastrointestinal tract and the liver before reaching the systemic circulation. The first pass effect can reduce the bioavailability and the effectiveness of the drug, as some or most of the drug may be metabolized and inactivated before reaching the site of action.
