Which of the following are chemical markers that identity cells or molecules?
- A. Antibodies
- B. Antigens
- C. T cells B lymphocytes A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET G
Correct Answer: A
Rationale: Antibodies are proteins produced by the immune system that specifically recognize and bind to foreign molecules, such as antigens. They are chemical markers that facilitate the identification of cells or molecules by interacting with specific antigens. This interaction plays a crucial role in various immune responses, including immune surveillance, antigen recognition, and immune defense mechanisms. Antibodies are essential tools in biomedical research, diagnostics, and therapeutics for identifying and targeting specific cells or molecules.

the vital sign that the nurse should most certainly check before administering digoxin is:
- A. pulse rate
- B. temperature
- C. blood pressure
- D. respiratory rate 99- coarctation of the aorta reflects which of the statements?
Correct Answer: A
Rationale: Before administering digoxin, it is crucial for the nurse to check the patient's pulse rate. Digoxin is a medication commonly used to treat heart conditions such as atrial fibrillation and heart failure by increasing the strength and efficiency of the heart's contractions. However, digoxin can also cause adverse effects such as bradycardia (slow heart rate) or heart block. Therefore, it is important to assess the patient's pulse rate to ensure that it is within the safe range before administering digoxin.
Management of the foregoing patient should include:
- A. Regular diet with extra fruits and green vegetables
- B. Potassium-sparing diuretics
- C. Discontinuance of any oral magnesium salts
- D. All of the above measures
Correct Answer: C
Rationale: The patient's symptoms of muscle weakness and fatigue are likely due to hypermagnesemia, which is an excess of magnesium in the blood. Hence, the management should include discontinuing any oral magnesium salts that the patient may be taking. This will help in correcting the magnesium imbalance and improving the patient's symptoms. Regular diet modifications and potassium-sparing diuretics are not indicated for the treatment of hypermagnesemia and may not address the underlying cause in this case.
Which of the ff should the nurse include in the teaching plan of a client with acute bronchitis?
- A. Not coughing frequently
- B. Washing the hands frequently
- C. Consuming adequate calories
- D. Encouraging a semi-Fowler's position
Correct Answer: B
Rationale: In acute bronchitis, the highest priority in the teaching plan should focus on preventing the spread of infection. Washing hands frequently can help reduce the risk of spreading the infection to others or introducing new germs that could worsen the client's condition. Proper hand hygiene is one of the most important ways to prevent the transmission of respiratory infections, like bronchitis, by reducing the number of pathogens on the hands. This measure is important not only for the client's well-being but also for the health of those in close contact with the client.
A 57-year old patient had a right lower lobectomy. The nurse should initiate this action when the patient arrives from the Post Anesthesia Care Unit:
- A. immediately administer pain relief
- B. keep patient in semi-fowler's postion
- C. turn client every hour
- D. notify the family to report pateint's condition
Correct Answer: B
Rationale: After a right lower lobectomy, it is important to keep the patient in a semi-Fowler's position to promote lung expansion and oxygenation. This position helps to reduce pressure on the diaphragm and allows for better lung ventilation. By maintaining the patient in a semi-Fowler's position, it can help prevent complications such as atelectasis and pneumonia postoperatively. It is a crucial nursing intervention to ensure optimal respiratory function and promote recovery after lung surgery.
When can a donor and recipient of blood be considered compatible?
- A. If there is no change in the blood color when both samples are mixed in the laboratory
- B. If there are blood clots when both samples are mixed in the laboratory
- C. If there is no clumping or hemolysis when both samples are mixed in the laboratory
- D. If a blood drop does not sink when dropped in water after both samples are mixed in the laboratory
Correct Answer: C
Rationale: Compatibility between a donor and recipient of blood is determined by testing for compatibility of blood types. The most common blood typing systems are ABO and Rh. In compatibility testing, both the donor and recipient blood samples are mixed in the laboratory. If there is no clumping (agglutination) or hemolysis (rupture of red blood cells) observed when the samples are mixed, then the donor and recipient are considered compatible. Clumping or hemolysis indicates an incompatible blood transfusion, which can lead to serious complications like agglutination, blood clotting, or immune responses. Therefore, the absence of clumping or hemolysis is a key indicator of blood compatibility in transfusion medicine.
