What does preload refer to?
- A. The volume of blood entering the left side of the heart
- B. The volume of blood entering the right side of the heart
- C. The pressure in the venous system that the heart must overcome to pump the blood
- D. The pressure in the arterial system that the heart must overcome to pump the blood
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.

As a valued member of the team on your nursing care unit, you are trying to determine whether the team is doing well. Which of the following is a sign that your team is successful?
- A. Conflict occurs but is seen as an opportunity for team growth and development.
- B. No negative feelings are expressed, leading to everyone being happy and satisfied.

Rationale: One of the key indicators of a successful team is the ability to handle conflict positively. Conflict, when managed well, can lead to team growth and development. Choice B is incorrect because suppressing negative feelings does not indicate team success; open communication is crucial. Choice C is incorrect as successful teams view mistakes as learning opportunities rather than resorting to disciplinary action. Choice D is incorrect because successful teams are often innovative and willing to take risks rather than maintaining the status quo.
A client is complaining of pain that starts in the shoulder and travels down the length of his arm. This type of pain is referred to as:
- A. Referred pain
- B. Superficial pain
- C. Radiating pain
- D. Precipitating pain
Correct Answer: C
Rationale: Radiating pain is the correct term for pain that originates in one part of the body and extends to other related areas. In this scenario, the pain starting in the shoulder and traveling down the arm describes radiating pain. Referred pain (Choice A) is pain felt at a site different from the actual origin of the pain. Superficial pain (Choice B) is pain that arises from the skin or tissues just beneath it. Precipitating pain (Choice D) refers to pain that is triggered by specific actions or events, not the characteristic described in the question.
In which of the following ways can a healthcare provider promote the sense of taste for an older adult?
- A. Mixing foods together on the dinner tray
- B. Avoiding cologne, air fresheners, or room deodorizers
- C. Encouraging the client to chew food thoroughly
- D. Discouraging the use of salt or seasonings with prepared food
Correct Answer: C
Rationale: As individuals age, their sense of taste may diminish, impacting the enjoyment of eating. One effective way for a healthcare provider to promote the sense of taste for an older adult is by encouraging them to chew food thoroughly. Thorough chewing increases the contact of food with the taste buds, enhancing the chances of experiencing the flavors. Mixing foods together on the dinner tray may not necessarily enhance taste perception. Avoiding strong scents like cologne, air fresheners, or room deodorizers is more related to olfactory senses rather than taste. Discouraging the use of salt or seasonings can further diminish the taste experience for older adults who may already have reduced taste sensitivity.
When assisting a client with shampooing his hair while he is still in bed, a nurse raises the bed to approximately the level of her waist. What is the rationale for this action?
- A. To prevent shampoo from getting into the client's eyes
- B. To allow excess water to run off the edge of the bed
- C. To decrease strain on the nurse's back
- D. To prevent the client's hair from developing tangles
Correct Answer: C
Rationale: Raising the bed to the level of the nurse's waist while assisting a client with shampooing in bed is done to reduce strain on the nurse's back. This adjustment ensures that the nurse can work comfortably without excessive bending or stooping, thus preventing back injuries. Choices A, B, and D are incorrect. While preventing shampoo from getting into the client's eyes, allowing excess water to run off the bed, and preventing hair tangles are important considerations, the primary rationale for raising the bed is to prioritize the nurse's ergonomic safety and prevent musculoskeletal strain.
A client with an enlarged prostate is having trouble starting his flow of urine when using the bathroom. Another name for this condition is:
- A. Hesitancy
- B. Oliguria
- C. Retention
- D. Urgency
Correct Answer: A
Rationale: Urinary hesitancy occurs when a client has difficulty starting a flow of urine while using the bathroom. Hesitancy may be due to physiological factors, such as obstruction from an enlarged prostate, or due to psychological factors, such as anxiety or embarrassment. Oliguria refers to decreased urine output, retention is the inability to empty the bladder fully, and urgency is the sudden and strong need to urinate.
