1. What does preload refer to?

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

2. Which of the following is an example of a positive effect of exercise on a client?

Correct answer: C

Rationale: The correct answer is 'Decreased work of breathing.' Exercise has numerous positive effects on clients, such as increasing metabolic rate, improving gastric motility, and enhancing venous return. When a client exercises regularly, their work of breathing decreases, meaning that everyday activities require less exertion. This is beneficial as it indicates improved cardiovascular and respiratory efficiency. Choices A, B, and D are incorrect because a decreased basal metabolic rate, decreased venous return, and decreased gastric motility are not typically considered positive effects of exercise. Instead, an increased basal metabolic rate, improved venous return, and optimal gastric motility are desired outcomes associated with physical activity.

3. A client has just started a transfusion of packed red blood cells that a physician ordered. Which of the following signs may indicate a transfusion reaction?

Correct answer: A

Rationale: The correct answer is when the client suddenly complains of back pain and has chills. Signs of a transfusion reaction include back pain, chills, dizziness, increased temperature, and blood in the urine. These signs indicate a possible adverse reaction to the blood transfusion. Dependent edema in the extremities is not typically associated with a transfusion reaction. A seizure is not a common sign of a transfusion reaction unless it is due to severe complications. A decrease in heart rate to 60 bpm is not a typical sign of a transfusion reaction, but rather bradycardia may indicate other underlying conditions or medications.

4. Which of the following is classified as a prerenal condition that affects urinary elimination?

Correct answer: B

Rationale: A prerenal condition is one that causes reduced urinary elimination by affecting the blood flow to the kidneys. Pericardial tamponade is a condition that impacts the heart's ability to pump sufficient blood, leading to decreased blood flow to vital organs such as the kidneys. This reduction in blood flow to the kidneys can result in decreased urine production. The other choices, such as nephrotoxic medications, neurogenic bladder, and polycystic kidney disease, do not primarily affect the blood flow to the kidneys and are not classified as prerenal conditions that impact urinary elimination.

5. An adult patient is at the clinic for a physical examination. The patient states that they are feeling 'very anxious' about the physical examination. What steps can the nurse take to make the patient more comfortable?

Correct answer: A

Rationale: To help alleviate the patient's anxiety, the nurse should appear unhurried and confident during the examination. This can make the patient feel more at ease and reassured. It is important for the nurse to respect the patient's privacy by leaving the room while the patient changes unless assistance is needed. The patient should be instructed to change into an examining gown while leaving their undergarments on, providing a sense of comfort and familiarity. Additionally, measuring vital signs at the beginning of the examination can help gradually acclimate the patient to the process, making it less overwhelming. Therefore, the correct answer is to appear unhurried and confident when examining the patient. Choices B, C, and D are incorrect because they do not directly address the patient's anxiety or provide comfort in the same way as the correct answer.
