Nursing Elites

1. 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.

2. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.

3. A violation of a patient's confidentiality occurs if two nurses are discussing client information in which of the following scenarios?

• A. With a physical therapist treating the patient
• B. With a social worker planning for discharge
• C. With another nurse on duty to plan for break time
• D. In the hallway outside the patient's room

Correct answer: D

Rationale: The correct answer is 'In the hallway outside the patient's room.' Discussing client information in a public area like a hallway can potentially breach patient confidentiality as it increases the risk of unauthorized individuals overhearing sensitive information. Choices A, B, and C involve discussing client information with other healthcare professionals in appropriate settings, which are more likely to maintain patient confidentiality compared to discussing in a public space like a hallway. Option D is the correct choice because it highlights a scenario where patient information is at higher risk of exposure to unauthorized individuals, hence violating patient confidentiality.

4. A female client complains to the nurse at the health department that she has fatigue, shortness of breath, and lightheadedness. Her history reveals no significant medical problems. She states that she is always on a fad diet without any vitamin supplements. Which tests should the nurse expect the client to have first?

• A. peptic ulcer studies
• B. complete blood count, including hematocrit and hemoglobin
• C. genetic testing
• D. hemoglobin electrophoresis

Correct answer: B

Rationale: The correct answer is to perform a complete blood count, including hematocrit and hemoglobin, as the initial tests to assess the client's symptoms related to fatigue, shortness of breath, and lightheadedness. These symptoms can be indicative of anemia, which can be caused by nutritional deficiencies due to fad dieting without vitamin supplements. Peptic ulcer studies, genetic testing, and hemoglobin electrophoresis are not the most appropriate initial tests for the client's presenting symptoms and history. Peptic ulcer studies are not relevant to the client's symptoms. Genetic testing is not indicated based on the client's presentation and history. Hemoglobin electrophoresis is used to diagnose specific types of anemia and is not the first-line test in this scenario. Further testing decisions should be based on the results of the initial tests, the client's history, and other relevant factors.

5. The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:

• A. Manage peripheral edema
• B. Improve right ventricular function
• C. Increase pulmonary pressure
• D. Constrict the pulmonary vessels

Correct answer: B

Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.
