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.

To prevent baby bottle tooth decay, what should the nurse instruct?
- A. Water
- B. Milk
- C. Iron-fortified formula
- D. Unsweetened fruit juice
Correct Answer: A
Rationale: The correct answer is A: Water. Water is the best choice to prevent baby bottle tooth decay as it does not cause tooth decay and is a good option for bedtime bottles. Milk (choice B) and iron-fortified formula (choice C) contain sugars that can contribute to tooth decay. Unsweetened fruit juice (choice D) also contains natural sugars that can be harmful to the baby's teeth.
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.
What is a major goal for home care nurses?
- A. Restoring maximum health function.
- B. Promoting the health of populations.
- C. Minimizing the progress of disease.
- D. Maintaining the health of populations.
Correct Answer: A
Rationale: A major goal for home care nurses is restoring maximum health function. This involves helping patients achieve their highest level of health and independence, focusing on individualized care plans tailored to each patient's needs. Choice B, promoting the health of populations, is more aligned with public health nursing rather than home care nursing. Choice C, minimizing the progress of disease, is important but not as comprehensive as restoring maximum health function. Choice D, maintaining the health of populations, is more about preventive care at a population level rather than the individualized care provided by home care nurses.
The nurse knows that after receiving the blood from the blood bank, it should be administered within:
- A. 1 hour
- B. 2 hours
- C. 4 hours
- D. 6 hours
Correct Answer: D
Rationale: Blood transfusions need to be administered promptly after receiving the blood from the blood bank to ensure patient safety and effectiveness. Waiting too long can lead to complications such as bacterial growth in the blood product, which can be harmful when infused. Administering the blood within 6 hours is crucial to prevent such risks. Choices A, B, and C are incorrect because waiting for 1, 2, or 4 hours respectively can increase the likelihood of complications associated with delayed transfusion.
In monitoring the patient in PACU, the nurse correctly identifies that checking the patient's vital signs is done every:
- A. 1 hour
- B. 5 minutes
- C. 15 minutes
- D. 30 minutes
Correct Answer: A
Rationale: Correct Answer: A - Vital signs monitoring in the PACU (Post-Anesthesia Care Unit) is typically done every hour to closely monitor the patient's condition during the immediate postoperative period. This frequency allows the nurse to promptly identify any changes in the patient's vital signs and intervene as necessary. Choice B (5 minutes) is too frequent for routine vital signs monitoring in the PACU and may not allow for a comprehensive assessment of the patient's stability. Choice C (15 minutes) and Choice D (30 minutes) are also not in line with the standard practice of vital signs monitoring in the PACU, which is typically hourly.
