This study, which is an in-depth study of one boy, is a:
- A. case study
- B. longitudinal study
- C. cross-sectional study
- D. evaluative study
Correct Answer: A
Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.

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.
An adolescent client has bloodshot eyes, a voracious appetite, and dry mouth. Which drug abuse would the nurse most likely suspect?
- A. Marijuana
- B. Amphetamines
- C. Barbiturates
- D. Anxiolytics
Correct Answer: A
Rationale: The symptoms described, including bloodshot eyes, a voracious appetite, and dry mouth, are consistent with marijuana use. Bloodshot eyes are a common side effect of marijuana due to its effect on blood vessels in the eyes. Marijuana also often causes an increase in appetite (known as 'the munchies') and can result in dry mouth. Amphetamines typically cause symptoms like increased alertness, energy, and decreased appetite. Barbiturates and anxiolytics would not typically cause bloodshot eyes, a voracious appetite, and dry mouth as described in the scenario. Therefore, the most likely drug abuse the nurse would suspect in this case is marijuana.
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.
Which food is a high source of prebiotics?
- A. Chicken
- B. Garlic
- C. White rice
- D. Cheese
Correct Answer: B
Rationale: Garlic is the correct answer. It is high in prebiotics, which are non-digestible fibers that promote the growth of beneficial gut bacteria. Chicken, white rice, and cheese are not significant sources of prebiotics. Chicken is a good source of protein, white rice is a carbohydrate, and cheese is a dairy product, none of which are high in prebiotics.
Which of the following is not true about Pure Experimental research?
- A. There is a control group
- B. There is an experimental group
- C. Selection of subjects in the control group is randomized
- D. There is a careful selection of subjects in the experimental group
Correct Answer: D
Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.
