Nursing Elites

1. A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?

• A. 1.0 mEq/L
• B. 1.1 mEq/L
• C. 1.2 mEq/L
• D. 1.3 mEq/L

Correct answer: D

Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.

2. Why is starting a low CHO diet a contraindication for a client with renal insufficiency?

• A. As long as the client eats a minimum of 30g of CHO/day, there should be no problem.
• B. The client's clinical condition is a contraindication to starting a low CHO diet.
• C. Calcium supplements should be utilized to prevent the development of osteoporosis while on a low CHO diet.
• D. As long as the client eats foods that are high biologic protein sources, a low CHO diet can be followed.

Correct answer: B

Rationale: A client with renal insufficiency should not start a low CHO diet because it could result in an increased renal solute load. Clients with renal or liver disease require protein control in their diet to prevent complications. Proteins used must be of high biologic value, and protein intake is usually weight-based. Protein levels may be adjusted based on the client's clinical condition. A minimum level of carbohydrates is needed in the diet to spare protein. Vitamin and mineral supplements might be needed for clients with liver failure. The dietician plays a crucial role in calculating specific nutrient requirements for these clients and monitoring outcomes in conjunction with the healthcare team. Choice A is incorrect because simply consuming a minimum amount of carbohydrates does not address the issue of increased renal solute load. Choice C is incorrect as calcium supplements are not the primary concern when considering a low CHO diet for a client with renal insufficiency. Choice D is incorrect as the focus should be on the contraindication of a low CHO diet for a client with renal insufficiency rather than just high biologic protein sources.

3. A 27-year-old woman has delivered twins in the OB unit. The patient develops a condition of 5-centimeter diastasis recti abdominis. Which of the following statements is the most accurate when instructing the patient?

• A. Avoid sit-ups to prevent worsening the condition.
• B. Surgery is not always necessary for this condition.
• C. Guarding the abdominal region is important at this time.
• D. Antibiotics are not needed for diastasis recti abdominis.

Correct answer: C

Rationale: After experiencing diastasis recti abdominis, it is crucial for the patient to protect and guard the abdominal region to facilitate healing. Choice A is correct since avoiding sit-ups is important to prevent worsening the condition by increasing intra-abdominal pressure. Choice B is accurate as not all cases of diastasis recti abdominis require surgery; conservative management is often effective. Choice D is also correct as antibiotics are not indicated for diastasis recti abdominis since it is a separation of the abdominal muscles and not an infectious condition.

4. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:

• A. a maintenance dose.
• B. a loading dose.
• C. a medication with no first-pass effect.
• D. the medication to be given intravenously.

Correct answer: B

Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.

5. A client was involved in a motor vehicle accident in which the seat belt was not worn. The client is exhibiting crepitus, decreased breath sounds on the left, complains of shortness of breath, and has a respiratory rate of 34/min. Which of the following assessment findings should concern the nurse the most?

• A. temperature of 102°F and a productive cough
• B. arterial blood gases (ABGs) with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg
• C. trachea deviating to the right
• D. barrel-chested appearance

Correct answer: C

Rationale: The correct answer is 'trachea deviating to the right.' A mediastinal shift is indicative of a tension pneumothorax, which is a dangerous complication seen in trauma patients with symptoms like crepitus, decreased breath sounds, shortness of breath, and tachypnea. Assessing for acute traumatic injuries is crucial in this context. Choice A, a temperature of 102°F and a productive cough, is common in pneumonia cases and not as concerning as a mediastinal shift. Choice B, ABGs with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg, shows values within normal limits and does not suggest a tension pneumothorax. Choice D, a barrel-chested appearance, is typical of COPD and not directly related to the acute traumatic injury described. A tension pneumothorax is a medical emergency where air cannot escape the pleural cavity, leading to lung collapse and a mediastinal shift to the unaffected side with a downward displacement of the diaphragm.
