Nursing Elites

1. Because of the possible nervous system side-effects that occur with isoniazid (Nydrazid) therapy, which supplementary nutritional agent would the nurse teach the client to take as a prophylaxis?

• A. Alpha tocopherol (vitamin E)
• B. Ascorbic acid (vitamin C)
• C. Calcitriol (vitamin D)
• D. Pyridoxine (vitamin B6)

Correct answer: D

Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.

2. 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.

3. When giving an intramuscular injection to an infant, which of the following sites is preferred?

• A. Ventrogluteal region
• B. Deltoid
• C. Vastus lateralis
• D. Dorsogluteal region

Correct answer: C

Rationale: The correct answer is the Vastus lateralis when giving an intramuscular injection to an infant. The Vastus lateralis muscle, located in the thigh, is the preferred site for infants as it has a larger muscle mass and is well-developed, making it suitable for injections. The Ventrogluteal region and Dorsogluteal region are not recommended for infants due to their smaller muscle mass and potential risk of damaging nearby structures. The Deltoid muscle is typically used for older children and adults, not infants.

4. The nurse is assessing the newborn's respirations. Which of these findings would indicate a need for follow-up and further intervention?

• A. irregular respirations
• B. abdominal respirations
• C. shallow respirations
• D. 70 breaths per minute

Correct answer: D

Rationale: The ideal respiratory rate in a newborn is 30-60 breaths per minute. A respiratory rate of 70 breaths per minute indicates tachypnea and may require intervention. Therefore, a rate of 70 breaths per minute would necessitate follow-up and further intervention. Irregular, abdominal, and shallow respirations are common in newborns and may not necessarily indicate the need for immediate follow-up or intervention.

5. 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.
