Nursing Elites

1. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

2. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:

• A. Assist the client in using the bedside commode
• B. Administer stool softeners daily as prescribed
• C. Administer antidysrhythmics PRN as prescribed
• D. Maintain the client on strict bed rest

Correct answer: B

Rationale: Administering stool softeners daily as prescribed is essential to prevent straining during defecation, which can lead to a Valsalva maneuver. Straining can increase intra-abdominal pressure, hinder venous return, and elevate blood pressure, risking cardiac complications in a client recovering from a heart attack. Using a bedside commode might be useful to minimize exertion during toileting but does not directly address the risk of a Valsalva maneuver. Administering antidysrhythmics PRN is not the primary intervention for preventing a Valsalva maneuver; these medications are used to manage dysrhythmias if they occur. Keeping the client on strict bed rest is not the best option as early mobilization is encouraged in post-myocardial infarction recovery to prevent complications such as deep vein thrombosis and muscle weakness.

3. The nurse is caring for a 10-year-old upon admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: The correct answer is urinary output of 30 ml per hour. In a 10-year-old child, this level of urinary output is indicative of adequate fluid replacement without suggesting overload. Monitoring urinary output is crucial in assessing fluid balance. Choices B, C, and D are incorrect. No complaints of thirst do not provide a direct assessment of fluid status. Increased hematocrit is a sign of dehydration, not adequate fluid replacement. Good skin turgor around the burn is a general assessment but may not directly reflect the child's overall fluid status.

4. The nurse is caring for a 73-year-old man with cirrhosis. Which data obtained by the nurse during the assessment will be of most concern?

• A. The patient complains of right upper-quadrant pain upon palpation.
• B. The patient's hands flap back and forth when the arms are extended.
• C. The patient has ascites and a 2-kg weight gain from the previous day.
• D. The patient's skin has multiple spider-shaped blood vessels on the abdomen.

Correct answer: B

Rationale: The most concerning data obtained by the nurse is the patient's hands flapping back and forth when the arms are extended, indicating asterixis, which is associated with hepatic encephalopathy. This condition can progress to hepatic coma and requires immediate attention. The presence of spider angiomas and right upper-quadrant abdominal pain are common findings in cirrhosis and do not warrant urgent intervention. Although ascites and weight gain suggest the need for treatment, they are not as alarming as the neurologic manifestations seen in hepatic encephalopathy.

5. The nurse is providing discharge instructions to the mother of a child who had a cleft palate repair. Which statement should the nurse make to the mother?

• A. You should use an orthodontic nipple on the child's bottle.
• B. You need to use a plastic spoon to feed the child.
• C. You can allow the child to use a pacifier but only for 30 minutes at a time.
• D. You need to monitor the child's temperature for signs of infection using an oral thermometer.

Correct answer: A

Rationale: After a cleft palate repair, it is crucial to use an orthodontic nipple on the child's bottle to feed them appropriately. The mother should be instructed to give the child baby food or baby food mixed with water. It is important to avoid introducing straws, pacifiers, spoons, or fingers into the child's mouth for 7 to 10 days post-surgery to prevent complications. The use of a pacifier should be avoided for at least 2 weeks following the surgical repair to promote proper healing. Additionally, taking oral temperatures should be avoided, and alternative temperature monitoring methods should be utilized to reduce the risk of infection. Therefore, options B, C, and D are incorrect because they could potentially lead to complications or hinder the child's recovery after cleft palate repair.
