1. Which of the following is classified as a prerenal condition that affects urinary elimination?
- A. Nephrotoxic medications
- B. Pericardial tamponade
- C. Neurogenic bladder
- D. Polycystic kidney disease
Correct answer: B
Rationale: A prerenal condition is one that causes reduced urinary elimination by affecting the blood flow to the kidneys. Pericardial tamponade is a condition that impacts the heart's ability to pump sufficient blood, leading to decreased blood flow to vital organs such as the kidneys. This reduction in blood flow to the kidneys can result in decreased urine production. The other choices, such as nephrotoxic medications, neurogenic bladder, and polycystic kidney disease, do not primarily affect the blood flow to the kidneys and are not classified as prerenal conditions that impact urinary elimination.
2. Which of the following interventions is most appropriate for a client with a diagnosis of Risk for Activity Intolerance?
- A. Perform nursing activities throughout the entire shift
- B. Assess for signs of increased muscle tone
- C. Minimize environmental noise
- D. Teach clients to perform the Valsalva maneuver
Correct answer: C
Rationale: The most appropriate intervention for a client diagnosed with Risk for Activity Intolerance is to minimize environmental noise. Environmental noise can increase the energy demand on the client as they try to manage their responses to stimuli. By reducing excess noise, the nurse helps promote rest and conserves the client's energy, which is crucial in managing activity intolerance. Choice A is incorrect because increasing nursing activities may exacerbate the client's intolerance to activity. Choice B is incorrect as assessing for signs of increased muscle tone does not directly address the issue of activity intolerance. Choice D is incorrect as teaching the Valsalva maneuver is not relevant to managing activity intolerance in this scenario.
3. 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.
4. The nurse is unable to palpate the right radial pulse on a patient. What would the nurse do next?
- A. Auscultate over the area with a fetoscope.
- B. Use a goniometer to measure the pulsations.
- C. Use a Doppler device to check for pulsations over the area.
- D. Check for the presence of pulsations with a stethoscope.
Correct answer: C
Rationale: When a nurse is unable to palpate a radial pulse, the next step is to use a Doppler device to check for pulsations over the area. Doppler devices are specifically designed to augment pulse or blood pressure measurements. Auscultating with a fetoscope is used to listen to fetal heart tones and is not relevant in this scenario. Goniometers are used to measure joint range of motion and are not used to assess pulses. Stethoscopes are primarily used to auscultate breath, bowel, and heart sounds, not to check for pulsations in peripheral pulses. Therefore, the correct course of action when unable to palpate a pulse is to utilize a Doppler device to assess for pulsations in the radial pulse area.
5. Patients exhibiting signs of cyanosis will:
- A. show signs of hyperoxia.
- B. have increased O2 saturation.
- C. have blood levels of CO2 higher than O2 levels.
- D. None of the above.
Correct answer: C
Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.
