Nursing Elites

1. A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?

• A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
• B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
• C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
• D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.

Correct answer: A

Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.

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 63 mmHg, 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 indicate 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 due to hypoxia stimulating hyperventilation, but the given ABG values specifically point to hypoxia as the primary issue.

3. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36mmHg, and HCO3 24 mEq/L?

• A. metabolic alkalosis
• B. homeostasis
• C. respiratory acidosis
• D. respiratory alkalosis

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within normal ranges, indicating a state of balance in the body's acid-base levels. Choices A, C, and D are incorrect as the ABG values provided do not point towards metabolic alkalosis, respiratory acidosis, or respiratory alkalosis. Instead, the values reflect a state of equilibrium where pH, PO2, PCO2, and HCO3 levels are within the normal range.

4. When planning care for a client taking Heparin, which nursing diagnosis should the nurse address first?

• A. Ineffective tissue perfusion related to the presence of a thrombus obstructing blood flow
• B. Risk for injury related to active loss of blood from the vascular space
• C. Deficient knowledge related to the client's lack of understanding of the disease process
• D. Impaired skin integrity related to the development of bruises and/or hematoma

Correct answer: B

Rationale: The correct answer is 'Risk for injury related to active loss of blood from the vascular space.' When a client is taking Heparin, the primary concern is the risk of bleeding due to its anticoagulant properties. Monitoring for signs of active blood loss is crucial to prevent complications like hemorrhage. While ineffective tissue perfusion, deficient knowledge, and impaired skin integrity are important, they are secondary to the immediate risk of bleeding in clients taking anticoagulants like Heparin.

5. In alcoholics with anemia:

• A. Pernicious anemia is more common than folic acid deficiency.
• B. Iron deficiency and folic acid deficiency can coexist.
• C. The alcohol interferes with iron absorption.
• D. Oral vitamin replacement is contraindicated.

Correct answer: B

Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.
