1. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?
- A. Continue taking warfarin until the day of surgery.
- B. Stop taking warfarin three days before surgery.
- C. Switch to aspirin before surgery.
- D. Stop taking warfarin one week before surgery.
Correct answer: D
Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.
2. When educating a mother about the benefits of breastfeeding, what should be included?
- A. Breastfeeding reduces the risk of postpartum hemorrhage.
- B. Breastfeeding provides passive immunity to the infant.
- C. Breastfeeding increases the mother's risk of breast cancer.
- D. Breastfeeding delays the return of menstruation.
Correct answer: B
Rationale: Breastfeeding provides passive immunity to the infant by transferring antibodies from the mother to protect the infant from infections and illnesses. This is one of the key benefits of breastfeeding, as it helps boost the baby's immune system during the early stages of life.
3. What is a primary function of macronutrients in the body?
- A. Regulate metabolic processes.
- B. Supply energy.
- C. Maintain homeostasis.
- D. Control cellular activity.
Correct answer: B
Rationale: The correct answer is B: Supply energy. The primary function of macronutrients such as carbohydrates, fats, and proteins is to supply energy for various bodily functions. Choices A, C, and D are incorrect because while regulating metabolic processes, maintaining homeostasis, and controlling cellular activity are essential functions in the body, they are not the primary roles of macronutrients. Macronutrients mainly serve as a source of energy to support daily activities and bodily functions.
4. Which symptom is most commonly associated with generalized anxiety disorder (GAD)?
- A. Frequent panic attacks
- B. Persistent and excessive worry
- C. Recurrent, intrusive thoughts
- D. Compulsive behaviors
Correct answer: B
Rationale: The correct answer is B: Persistent and excessive worry. Generalized anxiety disorder (GAD) is characterized by persistent and excessive worry about a variety of things, even when there is little or no reason to worry. This worry is difficult to control and can significantly impact daily life. While panic attacks, recurrent intrusive thoughts, and compulsive behaviors can occur in other anxiety disorders, persistent and excessive worry is the hallmark symptom of GAD. Therefore, choices A, C, and D are incorrect as they do not represent the primary symptom associated with GAD.
5. A postpartum client who delivered a healthy newborn is being assessed by a nurse. Which finding would indicate a complication during the early postpartum period?
- A. Moderate lochia rubra
- B. Bradycardia
- C. Elevated blood pressure
- D. Uterine contraction
Correct answer: C
Rationale: An elevated blood pressure in the postpartum period may indicate the onset of preeclampsia, a serious complication that requires immediate medical attention. Preeclampsia is characterized by high blood pressure, protein in the urine, and sometimes swelling in the hands and face. If left untreated, preeclampsia can lead to serious complications for both the mother and the baby. Therefore, it is crucial for healthcare providers to closely monitor blood pressure levels in postpartum clients to promptly address any signs of preeclampsia. Choices A, B, and D are not indicative of a complication during the early postpartum period. Moderate lochia rubra is a normal finding as it indicates the normal discharge of blood and tissue from the uterus after childbirth. Bradycardia, a slow heart rate, is not typically a concern in the absence of other symptoms or signs of distress. Uterine contractions are essential for involution and are expected in the postpartum period.
