Which of the following is NOT true of glucagon?
- A. produced by the pancreas
- B. increases blood glucose levels
- C. promotes the use of fat and protein instead of glucose
- D. stimulates the liver to store glucose as glycogen
Correct Answer: D
Rationale: The correct answer is D because glucagon actually stimulates the liver to release glucose into the bloodstream, not store glucose as glycogen. Glucagon helps increase blood glucose levels by promoting the breakdown of glycogen into glucose, and it also promotes the use of fat and protein for energy when glucose levels are low. Choices A, B, and C are all true statements about glucagon, making them incorrect options in this context.

Which one of the following is an appropriate nursing intervention for preparing a client for a CT scan?
- A. Consult the physician for the special preparation
- B. Provide general explanation to the client
- C. Inform client to temporarily eliminate salt from the diet
- D. Instruct the client to fast
Correct Answer: B
Rationale: Providing a general explanation to the client about the CT scan ensures they understand the procedure and prepares them psychologically for the test.
Which of the following is not a similarity between hormones and neurotransmitters?
- A. NONE OF THE ABOVE (all of the above are similarities between hormones and neurotransmitters)
- B. Both are chemical messengers.
- C. Both can sometimes be chemically identical.
- D. Both produce molecules that act on receptors.
Correct Answer: A
Rationale: The correct answer is A because it states that none of the above choices are similarities between hormones and neurotransmitters. This is accurate as choices B, C, and D all highlight similarities between hormones and neurotransmitters. Choice B is correct as both are chemical messengers, choice C is correct because some hormones and neurotransmitters can be chemically identical, and choice D is correct because both produce molecules that act on receptors. Therefore, A is the correct choice as it states that there are no similarities between the two, which is not the case.
A nurse is caring for a patient who has excessive catecholamine release. Which assessment finding would the nurse correlate with this condition?
- A. Decreased blood pressure
- B. Increased pulse
- C. Decreased respiratory rate
- D. Increased urine output
Correct Answer: B
Rationale: The correct answer is B: Increased pulse. Excessive catecholamine release, such as in a stress response, leads to sympathetic nervous system activation causing an increase in heart rate (pulse). This physiological response is known as the "fight or flight" response. Choices A, C, and D are incorrect as catecholamine release typically leads to increased blood pressure, increased respiratory rate, and decreased urine output due to vasoconstriction, increased oxygen demand, and fluid retention respectively.
Hormones often cause a cell to elicit multiple responses; this is because ________.
- A. there are thousands of receptors on the cell membrane
- B. the receptors bind to several hormones at the same time
- C. the protein kinases are rapidly metabolized
- D. during protein kinase activation, enzymes phosphorylate many other enzymes
Correct Answer: D
Rationale: The correct answer is D because during protein kinase activation, enzymes phosphorylate many other enzymes, leading to a cascade of signaling events that can trigger multiple responses in a cell. This process amplifies and diversifies the cellular response to hormones.
A: Choice A is incorrect because the number of receptors on the cell membrane does not directly relate to the ability of hormones to elicit multiple responses.
B: Choice B is incorrect because receptors typically bind to one hormone molecule at a time, not multiple hormones simultaneously.
C: Choice C is incorrect because the rapid metabolism of protein kinases does not directly explain why hormones can elicit multiple responses in a cell.
Jane Doe, 23, received her NPH insulin injection at 7:30 A.M., but due to oversight and a long wait in the x-ray department, she has not eaten for 14 hours. The nurse can anticipate which complication?
- A. Dehydration
- B. Ketoacidotic coma
- C. Insulin reaction
- D. Hyperosmolar hyperglycemic coma
Correct Answer: C
Rationale: Not eating after insulin injection can cause hypoglycemia, or an insulin reaction, due to the lack of food to balance the insulin effect.
