Nursing Elites

1. A nurse reviews a client’s urinalysis report. Which finding does the nurse recognize as abnormal?

• A. pH of 6.0
• B. An absence of protein
• C. The presence of ketones
• D. Specific gravity of 1.018

Correct answer: C

Rationale: The correct answer is C. The presence of ketones in the urine is abnormal. Ketones in the urine may indicate a state of ketosis, which is commonly seen in uncontrolled diabetes, fasting, or a low-carbohydrate diet. A normal pH range of urine is 4.5 to 7.8, making a pH of 6.0 within the normal range. An absence of protein is a normal finding in urine, as proteinuria (presence of protein) is abnormal. A specific gravity of 1.018 falls within the normal range of 1.016 to 1.022. Therefore, the presence of ketones is the abnormal finding in this scenario.

2. When preparing a client for intravenous pyelography (IVP), which action by the nurse is most important?

• A. Administering a sedative
• B. Encouraging fluid intake
• C. Administering an oral preparation of radiopaque dye
• D. Questioning the client about allergies to iodine or shellfish

Correct answer: D

Rationale: The most crucial action for the nurse when preparing a client for intravenous pyelography (IVP) is to question the client about allergies to iodine or shellfish. Some IVP dyes contain iodine, and if the client is allergic to iodine or shellfish, they may experience severe allergic reactions such as itching, hives, rash, throat tightness, difficulty breathing, or bronchospasm. Administering a sedative (Choice A) may be needed for relaxation during the procedure, encouraging fluid intake (Choice B) is generally beneficial but not the most crucial for IVP preparation, and administering radiopaque dye (Choice C) should only be done after confirming the client's safety regarding allergies to iodine or shellfish.

3. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:

• A. 85%
• B. 89%
• C. 95%
• D. 100%

Correct answer: C

Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.

4. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

5. A client is recovering after a nephrostomy tube was placed 6 hours ago. The nurse notes drainage in the tube has decreased from 40 mL/hr to 12 mL over the last hour. Which action should the nurse take?

• A. Document the finding in the client’s record.
• B. Evaluate the tube as working in the hand-off report.
• C. Clamp the tube in preparation for removing it.
• D. Assess the client’s abdomen and vital signs.

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to assess the client’s abdomen and vital signs. The nephrostomy tube should have a consistent amount of drainage, and a decrease may indicate obstruction. Before notifying the provider, the nurse must assess the client for pain, distention, and changes in vital signs. This assessment is crucial to gather essential information to report accurately. Documenting the finding without further assessment may delay necessary intervention. Evaluating the tube as working in the hand-off report or clamping the tube prematurely are not appropriate actions and could lead to complications if there is an obstruction.
