One of the dangers of treating hypernatremia is:
- A. Red blood cell crenation
- B. Cerebral edema
- C. Red blood cell hydrolysis
- D. Renal shutdown
Correct Answer: B
Rationale: Hypernatremia is a condition characterized by high levels of sodium in the blood. When hypernatremia is treated too rapidly or aggressively, a rapid decrease in serum sodium levels may occur. This rapid change in serum sodium concentration can cause water to move into brain cells, leading to cerebral edema. Cerebral edema is a dangerous complication associated with the potential to cause increased intracranial pressure, neurological deficits, and even death. It is crucial to correct hypernatremia slowly and carefully to prevent such complications.

Which of the ff. is a normal hemoglobin value?
- A. 38% to 48%
- B. 48 to 54 mg%
- C. 12 to 18 g/100mL
- D. 27 to 36 g/dL
Correct Answer: C
Rationale: The normal hemoglobin values are typically expressed in grams per deciliter (g/dL) or grams per 100 milliliters (g/100mL) of blood. The range of 12 to 18 g/100mL is considered the normal range for hemoglobin levels in adults. Hemoglobin values outside of this range may indicate various health conditions such as anemia or polycythemia. Option A (38% to 48%) is a range for hematocrit, not hemoglobin. Option B (48 to 54 mg%) and Option D (27 to 36 g/dL) are not within the standard normal range for hemoglobin levels.
A patient is treated with IV methylprednisolone (Solu-medrol) for emphysema. What is the purpose of corticosteroid treatment in lung disease?
- A. Dry secretions
- B. Improve the oxygen-carrying capacity
- C. Treat the infection that causes an of hemoglobin.
- D. Reduce airway inflammation.
Correct Answer: D
Rationale: Corticosteroids, such as methylprednisolone, are commonly used in the treatment of lung diseases like emphysema to reduce airway inflammation. In conditions like emphysema, inflammation in the airways can lead to symptoms such as shortness of breath and cough. Corticosteroids work by decreasing the inflammation in the airways, thereby helping to improve symptoms and slow down disease progression. By reducing inflammation, corticosteroids can also help to decrease mucus production and airway constriction, leading to improved lung function and overall respiratory health.
The nurse is planning care for a newborn receiving IV calcium gluconate for treatment of hypocalcemia. Which intervention is the most appropriate during the acute phase?
- A. Allow newborn to sleep with pacifier to decrease stimuli.
- B. Keep newborn awake to monitor central nervous system changes.
- C. Encourage parents to hold and feed newborn to facilitate attachment during illness.
- D. Awaken newborn periodically to assess level of consciousness.
Correct Answer: D
Rationale: During the acute phase of treatment with IV calcium gluconate for hypocalcemia in a newborn, it is essential to closely monitor the newborn's level of consciousness. Hypocalcemia can lead to central nervous system changes, such as irritability, jitteriness, and seizures. By awakening the newborn periodically to assess their level of consciousness, the nurse can promptly identify any signs of worsening central nervous system involvement and take appropriate action. This intervention ensures timely detection of any neurological complications and allows for timely intervention to prevent serious consequences. The other options do not address the importance of monitoring for central nervous system changes during the acute phase of treatment for hypocalcemia.
Several hours after returning from surgery, the nurse tells the patient that she is ordered to be ambulated. The patient asks, "Why?" Which of the following complications would the nurse correctly explain can be prevented by early postoperative ambulation?
- A. Increased peristalsis
- B. Coughing
- C. Pneumonia
- D. Wound healing  A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET K
Correct Answer: C
Rationale: Early postoperative ambulation is important for preventing complications such as pneumonia. When a patient remains immobile for an extended period after surgery, they are at an increased risk of developing pneumonia due to decreased lung expansion and secretions pooling in the lungs. Ambulation helps improve lung function, promote better oxygenation, and prevent respiratory complications like pneumonia. In contrast, increased peristalsis helps prevent constipation, coughing helps prevent respiratory complications as well, and wound healing is not directly related to the need for early postoperative ambulation.
Potential sources of mercury include all of the following EXCEPT
- A. swordfish
- B. old teething powders
- C. quicksilver
- D. milk
Correct Answer: D
Rationale: Mercury is not typically found in milk. It is commonly found in fish, old teething powders, quicksilver, and other sources.
