A 10 years old girl presented with fever and bruises for last 2 weeks. On examination she is pale; however there is no evidence of lymphadenopathy or hepatosplenomegaly. Her Hb is 6g/dl, TLC is 2700 and platelets are 90000. The most appropriate investigation to clinch the diagnosis is:
- A. Bone marrow aspiration
- B. Retics count
- C. Bleeding time
- D. PT and APTT
Correct Answer: A
Rationale: Bone marrow aspiration is essential to rule out conditions like aplastic anemia or leukemia, which could explain the symptoms and lab findings.
A neonate, who was delivered by Cesarean section for a breech presentation, is being examined in the neonatal nursery. For which of the following complications should the nurse carefully assess the baby?
- A. Developmental dysplasia of the hips (DDH)
- B. Legg-Calve-Perthes (LCP)
- C. Duchenne muscular dystrophy (DMD)
- D. Slipped capital femoral epiphysis (SCFE)
Correct Answer: A
Rationale: A neonate delivered by Cesarean section for a breech presentation is at higher risk for developmental dysplasia of the hips (DDH). Breech presentation, especially frank breech, increases the chance of hip instability and DDH due to the positioning of the legs in utero. DDH is a condition where the ball and socket joint of the hip does not properly form, leading to potential dislocation of the hip joint. It is important for the nurse to carefully assess the neonate for signs of hip dysplasia, such as limited hip abduction or asymmetry in the thigh folds, to facilitate early detection and intervention for optimal outcomes. Legg-Calve-Perthes (LCP), Duchenne muscular dystrophy (DMD), and slipped capital femoral epiphysis (SCFE) are not specifically related to breech delivery, and therefore, are less likely to be
Which of the ff. would the nurse explain to a patient is the main purpose of a hearing aid?
- A. Amplify background noise
- B. Amplify musical sounds
- C. Occlude the ear
- D. Improve ability to hear
Correct Answer: D
Rationale: The main purpose of a hearing aid is to improve the patient's ability to hear. Hearing aids are devices designed to amplify sound for individuals with hearing loss or difficulty hearing. They do not amplify background noise or musical sounds specifically; instead, they are meant to enhance the overall perception of sounds to help individuals better understand speech and communicate effectively. Moreover, hearing aids do not occlude the ear, but rather are used to transmit sound into the ear canal to make sounds louder and clearer for the wearer.
With severe diarrhea, electrolytes as well as fluids are lost. What electrolyte imbalance is indicated in Ms. CC's decreased muscle tone and deep tendon reflexes?
- A. Hypernatremia
- B. Hyperchoremia
- C. Hypokalemia
- D. Hypocalcemia
Correct Answer: C
Rationale: Hypokalemia is indicated in Ms. CC's decreased muscle tone and deep tendon reflexes. Potassium is an essential electrolyte for muscle function, including maintaining muscle tone and supporting proper nerve conduction for reflexes. When potassium levels are low, it can lead to muscle weakness, decreased muscle tone, and reduced deep tendon reflexes. With severe diarrhea, potassium is often lost along with fluids, leading to a potential electrolyte imbalance such as hypokalemia. Additionally, hypokalemia can cause cardiac arrhythmias, muscle cramps, and fatigue, further supporting the presence of this electrolyte imbalance in Ms. CC.
Nurse Amy teaches a group of nursing students about the factors that cuses biliary cirrhosis. Which factor is associated with the condition?
- A. acute viral hepatitis
- B. alcohol hepatotoxicity
- C. chronic biliary inflammation or obstruction
- D. hepatic failure with prolonged venous hepatic congestion
Correct Answer: C
Rationale: Primary biliary cirrhosis, now known as primary biliary cholangitis, is a chronic autoimmune liver disease that affects the bile ducts within the liver. The main characteristic of this condition is progressive destruction of the small bile ducts, leading to chronic biliary inflammation or obstruction. This results in the buildup of bile in the liver, causing damage and scarring (cirrhosis) over time. Factors such as acute viral hepatitis (choice A), alcohol hepatotoxicity (choice B), and hepatic failure with prolonged venous hepatic congestion (choice D) are associated with other liver conditions, but they are not specifically linked to primary biliary cholangitis.
