1. What is the abbreviation for micro drop?

• A. µgtt
• B. gtt
• C. mdr
• D. mgts

Correct answer: A

Rationale: The correct abbreviation for micro drop is 'µgtt,' where the symbol 'µ' represents micro and 'gtt' stands for drop. Choice B, 'gtt,' is the abbreviation for drop, not specifically for micro drop. Choice C, 'mdr,' and Choice D, 'mgts,' are not standard abbreviations for micro drop and are incorrect.

2. Which of the following is not a cause of tachycardia?

• A. Fever
• B. Exercise
• C. Sympathetic nervous system stimulation
• D. Parasympathetic nervous system stimulation

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.

3. After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

• A. Lethargy
• B. Increased pulse rate and blood pressure
• C. Muscle weakness
• D. Muscle irritability

Correct answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.

4. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

5. When providing mouth care to an unconscious client, what is the best position for the client?

• A. Fowler’s position
• B. Side-lying
• C. Supine
• D. Trendelenburg

Correct answer: B

Rationale: The best position for an unconscious client when providing mouth care is the side-lying position. This position helps prevent aspiration by allowing fluids to drain out of the mouth easily, reducing the risk of choking or aspiration pneumonia. Placing the client in a side-lying position also promotes comfort and safety during the procedure. The other options are not ideal for mouth care in an unconscious client: Fowler’s position may increase the risk of aspiration, the supine position can lead to aspiration as well, and Trendelenburg position is not recommended due to potential adverse effects on blood circulation and increased intracranial pressure.
