1. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.

2. A client who wears glasses is under the care of a nurse. Which of the following actions should the nurse take?

• A. Store the glasses in a labeled case.
• B. Clean the glasses with hot water
• C. Clean the glasses with a paper towel.
• D. Store the glasses on the bedside table.

Correct answer: A

Rationale: It is essential for the nurse to store the client's glasses in a labeled case to ensure they are kept safe and protected from damage. Storing them in a case helps prevent scratches, breakage, or misplacement. This practice promotes proper eyewear hygiene and ensures the client has their glasses readily available when needed. Cleaning the glasses with hot water or a paper towel can potentially damage the lenses or frames. Storing the glasses on the bedside table increases the risk of misplacement or damage.

3. 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.

4. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

5. A client is being educated by a healthcare provider on the purpose of taking a bronchodilator. Which of the following client statements indicates an understanding of the teaching?

• A. ''This medication can decrease my immune response.''
• B. ''I take this medication to prevent asthma attacks.''
• C. ''I need to take this medication with food.''
• D. ''This medication has a slow onset to treat my symptoms.''

Correct answer: B

Rationale: The correct answer is, 'I take this medication to prevent asthma attacks.' Bronchodilators are commonly used to relieve bronchospasm in conditions such as asthma. This medication helps to dilate the airways, making it easier to breathe and preventing asthma attacks. The other options are incorrect: option A is inaccurate as bronchodilators do not decrease immune responses, option C is incorrect as bronchodilators are typically taken on an empty stomach for better absorption, and option D is false as bronchodilators have a rapid onset to provide quick relief of symptoms.
