1. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

A. 10-15 seconds
B. 30-35 seconds
C. 20-25 seconds
D. 0-5 seconds

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.

2. You are to measure the client's initial blood pressure reading by doing all of the following EXCEPT:

A. Take the blood pressure reading on both arms for comparison
B. Listen to and identify the phases of Korotkoff sounds
C. Pump the cuff to around 50 mmHg above the point where the pulse is obliterated
D. Observe procedures for infection control

Correct answer: B

Rationale: When measuring blood pressure, it is crucial to follow specific steps to obtain accurate readings. Taking the blood pressure on both arms for comparison helps assess any variations. Pumping the cuff to around 50 mmHg above the point of pulse obliteration ensures accurate measurements. Observing procedures for infection control is vital to prevent the spread of infections. Listening to and identifying the phases of Korotkoff sounds are associated with auscultatory blood pressure measurements, not the initial blood pressure reading process.

3. Low levels of high-density lipoproteins (HDL) are?

A. associated with being underweight
B. more prevalent in males
C. highly predictive of CHD risk
D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

4. Which medical problem is not generally associated with malnutrition?

A. incontinence
B. pressure sores
C. celiac disease
D. major surgery

Correct answer: A

Rationale: Incontinence is not typically associated with malnutrition, whereas conditions like pressure sores and celiac disease are directly linked to nutritional deficiencies and malabsorption.

5. Dental hygienists should not encourage patients with eating disorders such as bulimia to brush immediately after vomiting because self-induced vomiting causes erosion of tooth enamel and dentin hypersensitivity.

A. Both the statement and the reason are correct and related
B. Both the statement and the reason are correct but are not related
C. The statement is correct, but the reason is not correct
D. The statement is not correct, but the reason is correct

Correct answer: D

Rationale: The corrected question emphasizes that patients with eating disorders like bulimia should not brush immediately after vomiting as it can worsen enamel erosion due to the acidic content in the mouth. The correct answer is D because patients should rinse with water or a fluoride mouthwash instead of brushing to protect their teeth. Choice A is incorrect because encouraging patients to brush after vomiting is not recommended. Choice B is incorrect as the reason provided is valid but not suitable for the action of encouraging brushing. Choice C is incorrect as the reason for not brushing after vomiting is to prevent enamel erosion.
