Ketosis and acidosis are:
- A. most apt to be caused by an excess of insulin.
- B. characteristic of diabetes insipidus.
- C. best treated with ADH.
- D. indicative of a rapid and incomplete metabolism of fatty acids.
Correct Answer: D
Rationale: The correct answer is D because ketosis and acidosis are indicative of a rapid and incomplete metabolism of fatty acids. Ketosis occurs when the body breaks down fats for energy, leading to high levels of ketones in the blood. Acidosis results from the accumulation of acidic substances in the body due to incomplete metabolism. Choices A, B, and C are incorrect because excess insulin does not cause ketosis and acidosis, diabetes insipidus is unrelated to these conditions, and ADH (antidiuretic hormone) is not the appropriate treatment for ketosis and acidosis.

The release of cortisol is stimulated by
- A. aldosterone
- B. angiotensin
- C. antidiuretic hormone (ADH)
- D. adrenocorticotropic hormone (ACTH)
Correct Answer: D
Rationale: The correct answer is D: adrenocorticotropic hormone (ACTH). ACTH is released by the pituitary gland in response to stress or low cortisol levels, stimulating the adrenal glands to release cortisol. Aldosterone (A) regulates electrolyte balance, angiotensin (B) regulates blood pressure, and antidiuretic hormone (C) regulates water balance, but they do not directly stimulate cortisol release. So, ACTH is the correct choice for stimulating cortisol production.
All of the following are hormones of the anterior pituitary except:
- A. Human growth hormone (GH).
- B. Follicle-stimulating hormone (FSH).
- C. Parathyroid hormone(PTH).
- D. Thyroid-stimulating hormone (TSH).
Correct Answer: C
Rationale: The correct answer is C: Parathyroid hormone (PTH). The anterior pituitary gland secretes hormones that regulate various bodily functions, such as growth, reproduction, and metabolism. PTH is actually produced by the parathyroid glands, not the anterior pituitary. Human growth hormone (GH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH) are all hormones secreted by the anterior pituitary gland. Therefore, C is the correct answer as it is not a hormone produced by the anterior pituitary gland.
Pituitary Hormone Triggering the Male Testes to Generate Sperm and in Females, Triggering Follicular Development Every Month Is
- A. Prolactin
- B. Growth hormone
- C. Follicle-stimulating hormone
- D. Luteinizing hormone
Correct Answer: C
Rationale: The correct answer is C: Follicle-stimulating hormone (FSH). FSH is responsible for triggering follicular development in females and sperm production in males. In females, FSH stimulates the growth and maturation of ovarian follicles, leading to the release of an egg during ovulation. In males, FSH stimulates the Sertoli cells in the testes to support the development of sperm.
A: Prolactin is not involved in the process of follicular development or sperm production.
B: Growth hormone is not directly related to the regulation of reproductive functions.
D: Luteinizing hormone (LH) is responsible for ovulation in females and testosterone production in males, but it is not the hormone that triggers follicular development or sperm production.
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.
The nurse assesses the diabetic patient's technique of self-monitoring of blood glucose (SMBG) 3 months after initial instruction. Which error in the performance of SMBG noted by the nurse requires intervention?
- A. Doing the SMBG before and after exercising
- B. Puncturing the finger on the side of the finger pad
- C. Cleaning the puncture site with alcohol before the puncture
- D. Holding the hand down for a few minutes before the puncture
Correct Answer: C
Rationale: Alcohol on the skin can interfere with glucose readings and should not be used to clean the puncture site.
