Which of the following lab values is associated with a decreased risk of cardiovascular disease?
- A. high HDL cholesterol
- B. low HDL cholesterol
- C. low total cholesterol
- D. low triglycerides
Correct Answer: B
Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

Which of the following foods should be avoided by clients who are prone to developing heartburn as a result of gastroesophageal reflux disease (GERD)?
- A. lettuce
- B. eggs
- C. chocolate
- D. butterscotch
Correct Answer: C
Rationale: The correct answer is chocolate. Ingestion of chocolate can reduce lower esophageal sphincter (LES) pressure, leading to reflux and clinical symptoms of GERD. Lettuce and eggs do not significantly affect LES pressure, making them less likely to trigger GERD symptoms. Butterscotch, like lettuce and eggs, does not have a notable effect on LES pressure, so it is not as likely to worsen GERD symptoms as chocolate. Therefore, chocolate is the food to be avoided by clients prone to heartburn due to GERD.
What should be included in the assessment of a client with a cast?
- A. capillary refill, warm toes, no discomfort.
- B. posterior tibial pulses, warm toes.
- C. moist skin essential, pain threshold.
- D. discomfort of the metacarpals.
Correct Answer: A
Rationale: When assessing a client with a cast, it is crucial to check for capillary refill to ensure adequate circulation. Warm toes indicate good circulation, while the absence of discomfort suggests the cast is not causing any pain or undue pressure on the client. Therefore, choices B, C, and D are incorrect as they do not address the essential components of assessing a client with a cast.
Why might breast implants interfere with mammography?
- A. They might cause additional discomfort.
- B. They are contraindications to mammography.
- C. They are likely to be dislodged.
- D. They might prevent detection of masses.
Correct Answer: D
Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.
Why is client and family communication and education concerning restraints essential?
- A. confuses both groups further
- B. helps with coping and stress levels
- C. encourages cooperation with the client and family
- D. puts the responsibility on the client and family, not the nurse
Correct Answer: C
Rationale: Client and family communication and education concerning restraints are essential to encourage cooperation. When the client and family understand the purpose and expected benefits of restraints, they are more likely to cooperate. This understanding can help prevent well-meaning family members from releasing restraints due to confusion or lack of information. Therefore, choice C is correct. Choices A, B, and D are incorrect because confusing both groups further, helping with coping and stress levels, and shifting responsibility to the client and family are not the primary goals of communication and education concerning restraints.
Signs of internal bleeding include all of the following except:
- A. painful or swollen extremities
- B. a tender, rigid abdomen
- C. vomiting bile
- D. bruising
Correct Answer: C
Rationale: Vomiting bile is not typically a sign of internal bleeding but is more commonly associated with issues in the gastrointestinal tract. Signs of internal bleeding include painful or swollen extremities, a tender, rigid abdomen, and bruising. Painful or swollen extremities can indicate bleeding from an extremity injury, a tender, rigid abdomen can signal abdominal bleeding, and bruising can result from blood vessel damage. Therefore, the correct answer is 'C: vomiting bile,' as it is not a typical sign of internal bleeding.
