Nursing Elites

1. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

2. The LPN participates in a home visit for a client with Type 2 Diabetes who has been taking Metformin for 3 years. The client states that for the past 3 months, they have been trying a vegan diet and experiencing fatigue, confusion, and mood changes. What is a likely cause of the new symptoms?

• A. vitamin B12 deficiency
• B. chronic hypoglycemia
• C. vitamin D deficiency
• D. increased tolerance to Metformin

Correct answer: A

Rationale: The correct answer is vitamin B12 deficiency. Long-term use of Metformin can lead to vitamin B12 deficiency, and a vegan diet is low in vitamin B12. Symptoms of vitamin B12 deficiency include anemia, fatigue, confusion, and mood changes. Chronic hypoglycemia is unlikely in a client with Type 2 Diabetes who has been taking Metformin as it typically causes hyperglycemia. Vitamin D deficiency usually presents with symptoms related to bones and muscles, not confusion and mood changes. Increased tolerance to Metformin does not explain the client's new symptoms, which are more indicative of a nutritional deficiency like vitamin B12.

3. When determining a fetal heart rate (FHR) and noting accelerations from the baseline rate when the fetus is moving, a nurse interprets this finding as:

• A. A reassuring sign
• B. An indication of the need to contact the physician
• C. An indication of fetal distress
• D. A nonreassuring sign

Correct answer: A

Rationale: When a nurse notes accelerations from the baseline rate of the fetal heart rate, particularly when they occur with fetal movement, it is considered a reassuring sign. This indicates a healthy response to fetal activity. Reassuring signs in FHR monitoring include an average rate between 120 and 160 beats/min at term, a regular rhythm with slight fluctuations, accelerations from the baseline rate (often associated with fetal movement), and the absence of decreases from the baseline rate. Choices B, C, and D are incorrect because accelerations in FHR with fetal movement are not indicative of the need to contact the physician, fetal distress, or a nonreassuring sign. These signs would typically be associated with other abnormal FHR patterns that would warrant further assessment and intervention.

4. When a 25-year-old client complains of chest congestion and cough after previously presenting with cold symptoms, what data should the nurse collect?

• A. Data related to follow-up care
• B. A complete health database
• C. Data related to the respiratory system
• D. Data related to the treatment for the cold

Correct answer: C

Rationale: In this case, the nurse should collect data related to the respiratory system since the client is presenting with symptoms like chest congestion and cough, indicating a respiratory issue. Focusing on the respiratory system will help gather pertinent information to assess the current problem comprehensively. A complete health database involves a detailed health history and full physical examination, which is beyond the immediate scope of the presenting issue. Data related to follow-up care is premature as the primary focus should be on assessing the current respiratory symptoms. Data related to the treatment for the cold is not the priority at this stage, as understanding the underlying respiratory problem is crucial for appropriate intervention.

5. What is the primary nutritional deficiency of concern for a strict vegetarian?

• A. vitamin C
• B. vitamin B12
• C. vitamin E
• D. magnesium

Correct answer: B

Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.
