Nursing Elites

1. Which hormone is responsible for amenorrhea in the pregnant woman?

• A. Progesterone
• B. Estrogen
• C. Follicle-stimulating hormone (FSH)
• D. Human chorionic gonadotropin (hCG)

Correct answer: A

Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.

2. When preparing a client for platelet pheresis in the blood bank, which information is most significant to obtain during the history assessment?

• A. Allergies to shellfish
• B. Date of last platelet donation
• C. Time of last oral intake
• D. Blood type

Correct answer: B

Rationale: The most significant information to gather when a client is scheduled for platelet pheresis is the date of their last platelet donation. Platelet donors can typically have their platelets apheresed as frequently as every 14 days. Knowing the date of the last donation helps ensure the client is eligible for the procedure without risking any adverse effects from frequent donations. Allergies to shellfish may be important for other procedures where anticoagulants containing heparin are used, but it is not directly related to platelet pheresis. The time of the last oral intake is more crucial for procedures requiring sedation or anesthesia. Blood type is significant for blood transfusions but is not the primary concern for platelet pheresis.

3. A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?

• A. Depressed function of the CNS
• B. Increased blood flow
• C. Decreased venous capacity
• D. Pain relief

Correct answer: C

Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.

4. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

5. Which infection control measure is the priority for the nurse to implement in the care provided for a child admitted to the hospital with bacterial meningitis?

• A. Place the child in a private room
• B. Gowns and masks must be worn by all personnel in the child's room
• C. Visitors are restricted to parents only
• D. Hand washing is required by all personnel and visitors having contact with the child

Correct answer: B

Rationale: The priority control measure for the nurse to implement in caring for a child with bacterial meningitis is ensuring that gowns and masks are worn by all personnel in the child's room. This measure is crucial as the child with bacterial meningitis is contagious for at least 24 hours after starting antibiotics, necessitating airborne precautions to prevent the spread of infection to healthcare workers and other patients. Placing the child in a private room (Choice A) is important but secondary to preventing infection transmission. Restricting visitors to parents only (Choice C) is also significant but not as critical as ensuring proper infection control measures. While hand washing (Choice D) is essential, the immediate need to prevent airborne transmission in the child's room takes precedence.
