1. During lactation, where is lactose synthesized in the body?
- A. Liver
- B. Breast
- C. Kidney
- D. Pancreas
Correct answer: B
Rationale: The correct answer is B: Breast. Lactose is synthesized in the breast during lactation to produce breastmilk. The liver is responsible for various metabolic functions but does not synthesize lactose. The kidney's primary role is in filtering blood and regulating electrolytes, not lactose synthesis. The pancreas is involved in producing digestive enzymes and insulin, not lactose synthesis.
2. What is the primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT)?
- A. No need for regular INR monitoring
- B. Lower risk of bleeding
- C. Fewer dietary restrictions
- D. Longer half-life
Correct answer: A
Rationale: The primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT) is that rivaroxaban does not require regular INR monitoring. This eliminates the need for frequent blood tests to adjust the dosage, making it more convenient for patients to manage their anticoagulant therapy.
3. Which symptom is most indicative of posttraumatic stress disorder (PTSD)?
- A. Persistent low mood
- B. Frequent nightmares
- C. Hallucinations
- D. Compulsive behaviors
Correct answer: B
Rationale: Frequent nightmares are a hallmark symptom of posttraumatic stress disorder (PTSD). Individuals with PTSD often experience intrusive and distressing nightmares related to the traumatic event they have experienced. These nightmares can contribute to sleep disturbances and further exacerbate the individual's overall psychological distress. Persistent low mood, hallucinations, and compulsive behaviors are not specific symptoms of PTSD and are more commonly associated with other mental health conditions such as depression, psychotic disorders, and obsessive-compulsive disorder respectively.
4. Following delivery, the nurse places the newborn under a radiant heat warmer. Which of the following is this action used to prevent?
- A. Cold stress
- B. Hyperthermia
- C. Dehydration
- D. Hypoxia
Correct answer: A
Rationale: Placing the newborn under a radiant heat warmer is used to prevent cold stress. Cold stress in newborns can lead to increased oxygen consumption and energy expenditure as the body tries to maintain its temperature, potentially resulting in hypoglycemia and metabolic acidosis if not addressed. The radiant warmer helps maintain the infant's body temperature, reducing the risk of cold stress and its complications. Choices B, C, and D are incorrect because the primary purpose of using a radiant warmer in this scenario is to prevent cold stress specifically, not hyperthermia, dehydration, or hypoxia.
5. A 3-year-old child has been admitted to your pediatric ward. The doctor gave a provisional diagnosis of respiratory tract infection. After careful assessment and history, a final diagnosis of lower respiratory infection was made. Which of the following signs will confirm the diagnosis?
- A. Cough
- B. Fever
- C. Inability to lie supine
- D. Inability to eat
Correct answer: C
Rationale: Inability to lie supine is a characteristic sign of lower respiratory infection. This positioning preference is often seen in patients with lower respiratory infections due to discomfort or difficulty breathing when lying flat on their back. While cough and fever are common symptoms associated with respiratory infections, they are not specific to lower respiratory infections. Inability to eat may indicate general illness or discomfort but is not a specific indicator of lower respiratory infection.
