Nursing Elites

1. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which clinical finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD receiving supplemental oxygen, the use of accessory muscles is a critical finding that requires immediate intervention. This observation indicates increased work of breathing, suggesting respiratory distress. Addressing this issue promptly is crucial to prevent further respiratory compromise. Choice A, oxygen saturation of 90%, is slightly below the normal range but may not require immediate intervention unless it continues to decrease. Choice B, a respiratory rate of 24 breaths per minute, is within normal limits for an adult and does not indicate an urgent issue. Choice D, inspiratory crackles, may be present in COPD due to secretions or inflammation but do not necessitate immediate intervention unless associated with other concerning signs.

2. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

3. While caring for a toddler receiving oxygen (02) via face mask, the nurse observes that the child's lips and nares are dry and cracked. Which intervention should the nurse implement?

• A. Ask the mother what she usually uses on the child's lips and nose.
• B. Apply a petroleum jelly (Vaseline) to the child's nose and lips.
• C. Use a topical lidocaine (Zylocaine viscous) analgesic for cracked lips.
• D. Use a water-soluble lubricant on affected oral and nasal mucosa.

Correct answer: D

Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.

4. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should be reported to the healthcare provider before the procedure?

• A. Serum creatinine of 2.5 mg/dL
• B. Serum potassium of 6.5 mEq/L
• C. Serum calcium of 8 mg/dL
• D. Serum bicarbonate of 24 mEq/L

Correct answer: B

Rationale: The correct answer is B. A serum potassium level of 6.5 mEq/L is dangerously high and should be reported before hemodialysis to prevent cardiac complications. High potassium levels can lead to life-threatening arrhythmias. Serum creatinine (Choice A) is elevated in renal dysfunction but not the most critical value to report before hemodialysis. Serum calcium (Choice C) and serum bicarbonate (Choice D) levels are within normal limits and are not immediate concerns before hemodialysis.

5. A male client with diabetes mellitus type 2, who is taking pioglitazone PO daily, reports to the nurse the recent onset of nausea, accompanied by dark-colored urine, and a yellowish cast to his skin. What instructions should the nurse provide?

• A. Seek immediate medical assistance to evaluate the cause of these symptoms.
• B. Discontinue the medication and follow up with a healthcare provider.
• C. Increase fluid intake and monitor urine color.
• D. Continue taking the medication and report any changes.

Correct answer: A

Rationale: The correct answer is A: 'Seek immediate medical assistance to evaluate the cause of these symptoms.' The symptoms described by the client, including nausea, dark-colored urine, and yellowish skin, are indicative of possible liver toxicity, a serious side effect of pioglitazone. Therefore, immediate medical evaluation is necessary to assess the severity of the condition and prevent further complications. Choices B, C, and D are incorrect: B advises discontinuing the medication without seeking immediate medical assistance, which could delay necessary treatment; C focuses solely on increasing fluid intake and monitoring urine color, overlooking the urgency of the situation; and D suggests continuing the medication when prompt evaluation is crucial in this scenario.
