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. When is the most appropriate time for obtaining a sputum specimen for culture?

• A. Early in the morning
• B. After the patient eats a light breakfast
• C. After aerosol therapy
• D. After chest physiotherapy

Correct answer: A

Rationale: Obtaining a sputum specimen early in the morning is the most appropriate time because secretions have accumulated overnight. This timing provides the best sample with the least contamination, leading to more accurate culture results and aiding in diagnosing respiratory infections effectively.

3. Which of the following actions will most likely lead to a break in the sterile technique for respiratory isolation?

• A. Opening the patient’s window to the outside environment
• B. Turning on the patient’s room ventilator
• C. Opening the door of the patient’s room leading into the hospital corridor
• D. Failing to wear gloves when administering a bed bath

Correct answer: D

Rationale: Failure to wear gloves during a bed bath can potentially introduce pathogens, compromising the sterile technique necessary for respiratory isolation. Proper hand hygiene and personal protective equipment are crucial to prevent the transmission of infectious agents in such settings.

4. What term refers to the manner of walking?

• A. Gait
• B. Range of motion
• C. Flexion and extension
• D. Hopping

Correct answer: A

Rationale: Gait specifically refers to the manner in which a person walks. It encompasses the pattern, rhythm, and style of walking, making it the most appropriate term in this context. Choices B, C, and D are incorrect. Range of motion refers to the extent of movement of a joint, flexion and extension relate to bending and straightening movements at a joint, and hopping is a specific type of movement that involves jumping on one foot.

5. A client in labor is receiving oxytocin. Which of the following findings indicates that the nurse should increase the rate of infusion?

• A. Urine output of 20 ml/hr.
• B. Montevideo units constantly at 300 mm Hg.
• C. FHR pattern showing absent variability.
• D. Contractions occurring every 5 minutes and lasting 30 seconds.

Correct answer: B

Rationale: Montevideo units measure the strength and frequency of contractions during labor. A consistent Montevideo units reading of 300 mm Hg or higher is indicative of effective uterine contractions. In this scenario, an increase in the rate of oxytocin infusion may be warranted to further augment contractions and promote progress in labor. The other options, such as low urine output, absent variability in fetal heart rate, and short contractions, do not directly correlate with the need for an increase in oxytocin infusion rate.
