Which of the following is least associated with the adrenal medulla?
- A. Catecholamines
- B. Epinephrine and norepinephrine
- C. Fight-or-flight response
- D. Sugar, salt, and sex
Correct Answer: D
Rationale: The correct answer is D because the adrenal medulla is primarily involved in the production of catecholamines, specifically epinephrine and norepinephrine, which are associated with the fight-or-flight response. This response is triggered by stress and prepares the body for action by increasing heart rate, dilating airways, and redirecting blood flow. On the other hand, the regulation of sugar, salt, and sex hormones is mainly controlled by the adrenal cortex, not the adrenal medulla. Therefore, while choices A, B, and C are directly related to the adrenal medulla's function, choice D is least associated with it.

A patient is hospitalized with adrenocortical insufficiency. Which nursing activity should you delegate to the nursing assistant?
- A. Remind patient to change positions slowly.
- B. Check the patient for muscle weakness.
- C. Teach the patient how to collect 24-hour urine.
- D. Plan nursing interventions to promote fluid balance.
Correct Answer: A
Rationale: Reminding the patient to change positions slowly is a non-invasive task that is appropriate for delegation to a nursing assistant, as it helps prevent dizziness or hypotension due to adrenocortical insufficiency.
Delegation Decision: The following interventions are planned for a diabetic patient. Which intervention can the nurse delegate to unlicensed assistive personnel (UAP)?
- A. Discuss complications of diabetes.
- B. Check that the bath water is not too hot.
- C. Check the patient's technique for drawing up insulin.
- D. Teach the patient to use a meter for self-monitoring of blood glucose.
Correct Answer: B
Rationale: The UAP can check the bath water temperature, but teaching and assessing insulin-related skills require nursing knowledge.
The hormone that stimulates the contraction of smooth muscle in the uterus is .
- A. follicle-stimulating hormone
- B. oxytocin
- C. prolactin
- D. luteinizing hormone
Correct Answer: B
Rationale: The correct answer is B: oxytocin. Oxytocin is the hormone responsible for stimulating the contraction of smooth muscle in the uterus during childbirth and labor. It acts on the smooth muscle cells in the uterine wall, causing them to contract and aiding in the process of childbirth.
A: Follicle-stimulating hormone is involved in the regulation of the reproductive system, particularly in the development of ovarian follicles.
C: Prolactin is primarily responsible for milk production in the mammary glands.
D: Luteinizing hormone triggers ovulation and the formation of the corpus luteum in the ovary.
Therefore, the correct answer is B because it directly affects the contraction of smooth muscle in the uterus, which is essential during childbirth.
Alexa, a 32-year-old woman, has been diagnosed with metabolic syndrome. Nursing interventions would include teaching her about the typical accompanying signs and symptoms, such as:
- A. Weight loss, malar rash, and pharyngitis.
- B. Hypothyroidism, podagra, and elevated fasting glucose.
- C. Violaceous rash, pitting peripheral edema, and palpitation.
- D. Hypertension, low HDL, and elevated triglycerides.
Correct Answer: D
Rationale: Metabolic syndrome is characterized by a combination of hypertension, low HDL cholesterol, elevated triglycerides, abdominal obesity, and elevated fasting glucose.
In a patient with central diabetes insipidus, what will the administration of ADH during a water deprivation test result in?
- A. Decrease in body weight
- B. Decrease in blood pressure
- C. Increase in urinary output
- D. Increase in urine osmolality
Correct Answer: D
Rationale: In central diabetes insipidus, administering ADH during a water deprivation test will result in an increase in urine osmolality due to the kidneys' ability to concentrate urine in response to ADH.
