Nokea
A client with pneumonia is receiving oxygen therapy. What assessment finding requires immediate intervention?
- A. Increased oxygen saturation of 96%.
- B. Oxygen saturation of 89%.
- C. Respiratory rate of 20 breaths per minute.
- D. Decreased heart rate of 70 beats per minute.
Correct Answer: B
Rationale: The correct answer is B. An oxygen saturation of 89% indicates hypoxemia, which is below the normal range (usually 95-100%). This finding requires immediate intervention as it signifies inadequate oxygenation. Options A, C, and D are within normal limits and do not indicate an urgent need for intervention. Option A indicates a good oxygen saturation level, option C denotes a normal respiratory rate, and option D suggests a normal heart rate. Therefore, these options do not require immediate intervention compared to the critically low oxygen saturation level of 89% in option B.

A 5-week-old infant with hypertrophic pyloric stenosis has developed projectile vomiting over the last two weeks. Which intervention should the nurse plan to implement?
- A. Instruct the mother to give sugar water only.
- B. Offer the infant oral rehydration every 2 hours.
- C. Provide Pedialyte feedings via nasogastric tube.
- D. Maintain intravenous fluid therapy.
Correct Answer: D
Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.
A client with chronic obstructive pulmonary disease (COPD) is being discharged home. What should the nurse include in the discharge teaching?
- A. Limit fluid intake to prevent lung congestion
- B. Avoid all physical activity to conserve energy
- C. Perform pursed-lip breathing during activities
- D. Increase oxygen flow rate if shortness of breath occurs
Correct Answer: C
Rationale: The correct answer is C. Pursed-lip breathing helps control breathing and improves oxygen exchange in clients with COPD. It can ease shortness of breath during activities and should be included in discharge teaching to manage symptoms. Option A is incorrect as adequate fluid intake is important for thinning mucus in COPD. Option B is wrong as physical activity, as tolerated, is beneficial for COPD patients. Option D is also incorrect because changing oxygen flow rate without healthcare provider guidance can be dangerous.
After a thyroidectomy, which vital sign is the most important for the nurse to monitor closely?
- A. Monitor respiratory rate and rhythm.
- B. Assess for signs of hypocalcemia.
- C. Monitor for elevated body temperature.
- D. Check blood pressure every 30 minutes.
Correct Answer: B
Rationale: The correct answer is B: Assess for signs of hypocalcemia. After a thyroidectomy, monitoring for hypocalcemia is crucial because damage to the parathyroid glands during surgery can result in low calcium levels, which may cause life-threatening complications. Monitoring respiratory rate and rhythm (choice A) is important but not the most critical in this situation. Monitoring for elevated body temperature (choice C) is less of a priority post-thyroidectomy. Checking blood pressure every 30 minutes (choice D) is not as vital as monitoring for hypocalcemia in this context.
Following a lumbar puncture, a client complains of worsening headache when sitting up. What complication is the client likely experiencing?
- A. A migraine headache
- B. An infection from the puncture site
- C. Low blood sugar
- D. Spinal fluid leakage (post-lumbar puncture headache)
Correct Answer: D
Rationale: The client is likely experiencing spinal fluid leakage (post-lumbar puncture headache), a common complication of a lumbar puncture. This leakage results in a reduction of cerebrospinal fluid volume around the brain and spinal cord, leading to a headache that worsens when in an upright position due to reduced buoyancy. A migraine headache (Choice A) is not typically associated with a lumbar puncture. Infection from the puncture site (Choice B) would present with localized signs of inflammation, such as redness, swelling, and warmth, rather than worsening headache. Low blood sugar (Choice C) is not a common complication of lumbar puncture and would not typically manifest as a worsening headache when sitting up.
A client admitted to the ICU with Syndrome of Inappropriate Antidiuretic Hormone (SIADH) has developed osmotic demyelination. What is the first intervention the nurse should implement?
- A. Evaluate the client's swallowing ability.
- B. Reorient the client frequently.
- C. Patch one eye to minimize confusion.
- D. Perform range of motion exercises.
Correct Answer: A
Rationale: The correct answer is to evaluate the client's swallowing ability. Osmotic demyelination can cause dysphagia, putting the client at risk for aspiration. Assessing swallowing function is crucial to prevent complications such as aspiration pneumonia. Reorienting the client frequently (Choice B) is more suitable for confusion related to conditions like delirium. Patching one eye (Choice C) is a technique used for diplopia or double vision, not specifically indicated for osmotic demyelination. Performing range of motion exercises (Choice D) may be beneficial for preventing complications of immobility but is not the priority intervention for osmotic demyelination.
