1. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?

A. Confusion
B. Pale skin
C. Bradycardia
D. Hypotension

Correct answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.

2. A client reports that the medication the nurse is administering appears different than what they take at home. Which of the following responses should the nurse take?

A. Did the doctor discuss with you that there was a change in this medication?
B. I recommend that you take this medication as prescribed
C. Do you know why this medication is being prescribed to you?
D. I will call the pharmacist now to check on this medication

Correct answer: A

Rationale: When a client reports that the medication appears different than what they take at home, it is crucial for the nurse to ensure the safety and accuracy of the medication being administered. The most appropriate action for the nurse to take in this situation is to call the pharmacist to verify the medication, dosage, and any potential changes. This proactive step helps prevent medication errors and ensures the client's safety and well-being.

3. Which of the following is the correct abbreviation for drops?

A. Gtt.
B. Gtts.
C. Dp.
D. Dr.

Correct answer: A

Rationale: The correct abbreviation for drops in medical terminology is 'Gtt.' It is derived from the Latin word 'guttae,' meaning drops. The abbreviation 'Gtts.' (Choice B) is incorrect as it adds an unnecessary 's.' Choices C and D, 'Dp.' and 'Dr.,' are not standard abbreviations for drops in medical contexts, making them incorrect.

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. 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.
