Evelyn was given iron as supplemental vitamin to prevent maternal anemia. She asks if
- A. Which of the following would be the best response of the nurse?
- B. "Take two other vitamins separately."
- C. Absorption of iron is enhanced with Vit C.
- D. "Drink milk when taking the iron supplement."
Correct Answer: C
Rationale: The correct response would be "Absorption of iron is enhanced with Vitamin C." Iron absorption is increased in the presence of Vitamin C. Therefore, recommending Evelyn to take her iron supplement with a source of Vitamin C such as orange juice or a Vitamin C tablet would optimize the absorption of iron in her body and help prevent maternal anemia more effectively. Taking iron with other vitamins separately, after a full meal, or with milk would not have the same beneficial effect on iron absorption as combining it with Vitamin C.

Which is the MOST important risk factor to osteoporosis
- A. Menopause
- B. With history of previous fracture
- C. Being male
- D. Short in height
Correct Answer: A
Rationale: Menopause is the most important risk factor for osteoporosis because it leads to a decrease in estrogen levels, which plays a crucial role in maintaining bone density. After menopause, women are at a higher risk of developing osteoporosis due to loss of estrogen's protective effects on bone mass. Other risk factors like history of previous fracture, being male, and short stature can also contribute to osteoporosis, but menopause has the strongest association with the development of the condition. It is essential for postmenopausal women to be aware of this risk factor and take preventive measures such as regular exercise, adequate calcium and vitamin D intake, and appropriate medical evaluation and treatment as needed.
A patient presents with acute pain, swelling, and deformity of the ankle following a twisting injury. X-ray reveals a fracture involving the distal fibula with associated widening of the ankle mortise. Which type of ankle fracture is most likely?
- A. Maisonneuve fracture
- B. Pilon fracture
- C. Tillaux fracture
- D. Trimalleolar fracture
Correct Answer: D
Rationale: A trimalleolar fracture is characterized by fractures involving the lateral malleolus (distal fibula), medial malleolus (distal tibia), and the posterior tubercle of the distal tibia. This fracture pattern results in instability of the ankle joint and is often associated with widening of the ankle mortise on X-ray. The deformity and swelling seen in this patient are indicative of a trimalleolar fracture and are typically caused by a high-energy injury, such as a forceful twisting motion. Treatment for trimalleolar fractures often involves surgical intervention to stabilize the ankle joint and restore normal function.
A patient with a history of coronary artery disease is scheduled for coronary artery bypass graft (CABG) surgery. Which preoperative nursing intervention is essential for preparing the patient for surgery?
- A. Administering aspirin to prevent thrombosis
- B. Providing education about postoperative pain management
- C. Assisting the patient with deep breathing and coughing exercises
- D. Obtaining informed consent for the surgical procedure
Correct Answer: C
Rationale: Preoperative nursing intervention that is essential for preparing a patient with a history of coronary artery disease for coronary artery bypass graft (CABG) surgery is assisting the patient with deep breathing and coughing exercises. These exercises are crucial to prevent postoperative complications such as atelectasis and pneumonia, which are common risks after surgery. Deep breathing exercises help to expand the lungs and improve ventilation, while coughing exercises help to clear secretions and prevent respiratory complications. By assisting the patient with these exercises preoperatively, the nurse can help optimize the patient's respiratory function and decrease the risk of complications during and after surgery. Administering aspirin, providing education about pain management, and obtaining informed consent are also important aspects of preoperative care, but assisting with deep breathing and coughing exercises is particularly essential for patients undergoing CABG surgery due to the increased risk of respiratory complications in this population.
Which of the following signs is indicative of shock in a trauma patient?
- A. Increased heart rate
- B. Hypertension
- C. Rapid capillary refill
- D. Hyperthermia
Correct Answer: C
Rationale: Rapid capillary refill is a sign indicative of shock in a trauma patient. Shock is a life-threatening condition where the body's organs and tissues do not receive adequate blood flow and oxygen, leading to cellular damage and eventual organ failure. In a trauma patient, rapid capillary refill suggests poor perfusion, which is a common feature of shock. The capillary refill time is an important clinical assessment that measures the time it takes for color to return to the nail bed after pressure is applied. In cases of shock, the refill time is faster than normal, indicating a systemic circulatory disturbance. Other signs of shock may include tachycardia (increased heart rate), hypotension (not hypertension), and hypothermia (not hyperthermia).
Human chorionic gonadotropin (HCG), the biologic marker on which pregnancy tests are based, can be detected in the BLOOD as early as which nber of DAYS after the last menstrual period?
- A. 15
- B. 10
- C. 20
- D. 5
Correct Answer: B
Rationale: Human chorionic gonadotropin (HCG) can be detected in the blood as early as 10 days after the last menstrual period. This hormone is produced by the placenta shortly after the embryo attaches to the uterine lining. Pregnancy tests detect HCG levels to determine pregnancy status, and the hormone can be detected earlier in the blood compared to urine tests. Detecting HCG in the blood at around 10 days post ovulation is often the earliest point when a blood test can confirm pregnancy.
