1. The nurse is reviewing percussion techniques with a new graduate nurse. Which action performed by the graduate nurse while percussing requires the nurse to intervene?
- A. Percussing twice over each area
- B. Striking with the fingertip, not the finger pad
- C. Using the wrist to make the strikes, not the arm
- D. Quickly lifting the striking finger after each stroke
Correct answer: A
Rationale: The correct answer is to percuss twice over each area, not once. This technique helps ensure a more accurate assessment. Striking with the fingertip instead of the finger pad is correct because the tip of the finger produces clearer sounds. Using the wrist to make the strikes instead of the arm is appropriate as it allows for more controlled and precise percussion. Quickly lifting the striking finger after each stroke is also correct to prevent damping off vibrations. Therefore, percussing once over each area (Choice A) is incorrect as it does not follow the standard percussion technique.
2. A healthcare professional is employed at a district health department and must spend several hours each day sitting at a desk. Which principle of ergonomics will most likely help them to reduce the risk of injury or pain in this situation?
- A. Adjust the chair height to keep the legs bent at the hips at a 90-degree angle
- B. Maintain the position of the computer monitor just below eye level
- C. Stand up and take a walk or stretch every 4 hours
- D. Rest wrists on the edge of the desk while typing
Correct answer: A
Rationale: When sitting for prolonged periods, it is important to adjust the height of the chair so that the legs are bent at the hips at a 90-degree angle. This position helps to reduce pressure on the back, legs, and feet, promoting better posture and reducing muscle fatigue. Standing up and moving around at least once every hour is crucial to support circulation and prevent stiffness. Maintaining the position of the computer monitor just below eye level helps reduce strain on the neck and eyes. Resting wrists on the edge of the desk while typing can lead to wrist strain and discomfort, so it is not an ergonomic recommendation for prolonged desk work.
3. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
4. A 75-year-old client, hospitalized with a cerebral vascular accident (stroke), becomes disoriented at times and tries to get out of bed but is unable to ambulate without help. What is the most appropriate safety measure?
- A. Restrain the client in bed
- B. Ask a family member to stay with the client
- C. Check the client every 15 minutes
- D. Use a bed exit safety monitoring device
Correct answer: D
Rationale: Option D is the most appropriate safety measure in this scenario. Using a bed exit safety monitoring device allows the client to retain some independence while ensuring that the nursing staff is alerted when assistance is needed. This solution promotes client safety without compromising their autonomy. Option A, restraining the client in bed, can lead to increased agitation, confusion, and a loss of independence. Option B, asking a family member to stay with the client, shifts the responsibility away from the healthcare team. Option C, checking the client every 15 minutes, is not a sufficient safety measure as the client could attempt to get out of bed in the unobserved interval, risking falls and injury.
5. A patient's nursing diagnosis is Insomnia. The desired outcome is: 'Patient will sleep for a minimum of 5 hours nightly by October 31.' On November 1, a review of the sleep data shows the patient sleeps an average of 4 hours nightly and takes a 2-hour afternoon nap. Which evaluation should be documented?
- A. Consistently demonstrated
- B. Often demonstrated
- C. Sometimes demonstrated
- D. Never demonstrated
Correct answer: D
Rationale: The correct answer is 'Never demonstrated.' Despite the patient sleeping a total of 6 hours daily, it is not achieved in one uninterrupted session at night as per the desired outcome. The patient's habit of taking a 2-hour afternoon nap also affects the evaluation. Therefore, the outcome should be evaluated as 'Never demonstrated.' Choice A, 'Consistently demonstrated,' is incorrect because the desired outcome of sleeping for a minimum of 5 hours nightly in one session is not met. Choice B, 'Often demonstrated,' is incorrect as the patient's sleep pattern does not consistently align with the desired outcome. Choice C, 'Sometimes demonstrated,' is also incorrect as the patient's sleep pattern does not meet the specific criteria set in the desired outcome.
