Which of the following lab values is associated with a decreased risk of cardiovascular disease?

Correct Answer: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.

Correct Answer: B

Rationale: The Apgar scoring system, developed by Virginia Apgar, an anesthesiologist, evaluates newborns based on five criteria: heart rate, respiratory effort, color, muscle tone, and reflex irritability. These parameters provide a quick and simple assessment of a newborn's overall condition and the need for immediate medical attention. Choices B, C, and D are incorrect as they do not encompass the essential elements evaluated by the Apgar scoring system.

Correct Answer: C

Rationale: Petrolatum gauze is recommended to be placed over the site when a physician removes a chest tube because it forms an airtight seal, helping prevent air from entering the pleural space. This airtight seal is crucial to avoid complications such as a pneumothorax. Transparent dressing is not ideal for this purpose as it may not provide a sufficient seal due to its design. Colloidal dressing and nonadherent dressing are also not suitable for chest tube removal sites as they do not offer the same level of protection against air leakage and may not provide the necessary sealing properties.

Correct Answer: C

Rationale: Termination in the nurse-client relationship should first be addressed in the orientation phase. This is because the client has a right to know the parameters of the relationship from the beginning. During the orientation phase, it is important to discuss if the relationship is time-limited, inform the client about the number of sessions, or explain that it is open-ended with the termination date to be negotiated later. Addressing termination in the orientation phase helps establish transparency and clear communication. Choices A, B, and D are incorrect because termination discussions should ideally start at the beginning of the relationship to set appropriate expectations.

Correct Answer: D

Rationale: Compulsive behavior is not a clinical sign typically associated with congestive heart failure (CHF). CHF commonly presents with symptoms such as increased body weight due to fluid retention, elevated heart rate as the heart works harder to pump blood effectively, and lower extremity edema caused by fluid buildup. While behavioral changes can occur in response to illness, compulsive behavior is not a typical indicator of CHF. Choices A, B, and C are more commonly linked to CHF and should be monitored in patients with this condition.
