Nursing Elites

1. A client on mechanical ventilation is experiencing high-pressure alarms. What action should the nurse implement first?

• A. Check the client's oxygen saturation.
• B. Assess the client's endotracheal tube for obstruction.
• C. Reposition the client to relieve pressure.
• D. Suction the client's airway.

Correct answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.

2. Which of these findings would the nurse more closely associate with anemia in a 10-month-old infant?

• A. Hemoglobin level of 12 g/dL
• B. Pale mucosa of the eyelids and lips
• C. Hypoactivity
• D. A heart rate between 140 to 160

Correct answer: B

Rationale: The correct answer is B. Pale mucous membranes, such as those of the eyelids and lips, are a classic sign of anemia in infants. Anemia leads to decreased oxygen-carrying capacity, resulting in tissue hypoxia, which can manifest as pale mucosa. Choice A, a hemoglobin level of 12 g/dL, is within the normal range for a 10-month-old infant and would not necessarily indicate anemia. Choice C, hypoactivity, is a non-specific finding and can be present in various conditions, not specifically anemia. Choice D, a heart rate between 140 to 160, is within the normal range for an infant and is not a specific finding associated with anemia.

3. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

4. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

5. A client is admitted with a suspected gastrointestinal bleed. What assessment finding requires immediate intervention?

• A. Bright red blood in the vomit.
• B. Elevated blood pressure and heart rate.
• C. Coffee ground emesis.
• D. Dark, tarry stools.

Correct answer: D

Rationale: Dark, tarry stools indicate the presence of digested blood in the gastrointestinal tract, signifying a higher gastrointestinal bleed. This finding requires immediate intervention due to the potential severity of the bleed. Bright red blood in the vomit may indicate active bleeding but is not as concerning as digested blood. Elevated blood pressure and heart rate are common responses to bleeding but do not provide direct evidence of the source or severity of the bleed. Coffee ground emesis is indicative of partially digested blood and is a concern but not as urgent as dark, tarry stools.
