1. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

2. For administering a cleansing enema, what is the common position typically used?

• A. Sims left lateral
• B. Dorsal Recumbent
• C. Supine
• D. Prone

Correct answer: A

Rationale: The correct position for administering a cleansing enema is the Sims left lateral position. This position is preferred as it helps to facilitate the procedure by allowing gravity to assist in the flow of the enema solution. The individual lies on their left side with the right knee flexed towards the chest, which helps to promote retention of the enema solution and its distribution throughout the colon. Choices B, C, and D are incorrect. The dorsal recumbent position (Choice B) is commonly used for physical examinations of the abdomen and genitalia. The supine position (Choice C) involves lying flat on the back and is not ideal for administering enemas. The prone position (Choice D) is lying flat on the stomach and is not suitable for administering enemas.

3. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

4. 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.

5. A client with tuberculosis is receiving a new prescription for isoniazid (INH). The nurse should instruct the client to report which of the following findings as an adverse effect of the medication?

• A. You might notice yellowing of your skin.
• B. You might experience pain in your joints.
• C. You might notice tingling of your hands.
• D. You might experience loss of appetite.

Correct answer: C

Rationale: Tingling of the hands is a common adverse effect of isoniazid (INH) due to its potential to cause peripheral neuropathy. This sensation can be an early sign of nerve damage, and thus, the client should be instructed to report it promptly to the healthcare provider for further evaluation and management.
