Nursing Elites

1. A client receiving drug therapy with furosemide and digitalis requires careful observation and care. In planning care for this client, the nurse should recognize that which of the following electrolyte imbalances is most likely to occur?

• A. hyperkalemia
• B. hypernatremia
• C. hypokalemia
• D. hypomagnesemia

Correct answer: C

Rationale: When a client is receiving drug therapy with furosemide and digitalis, the nurse should anticipate the development of hypokalemia due to the potassium-wasting effects of furosemide. Hypokalemia can potentiate digitalis toxicity. While hyperkalemia is a concern with some medications, it is not typically associated with furosemide and digitalis. Furosemide can lead to hyponatremia, not hypernatremia, due to its diuretic effect. Hypomagnesemia, though a possible imbalance, is not the most likely to occur in this scenario as furosemide and digitalis are more commonly associated with hypokalemia.

2. A nurse reviewed the arterial blood gas reading of a 25-year-old male. The nurse should be able to conclude the patient is experiencing which of the following conditions?

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

Correct answer: D

Rationale: The correct answer is respiratory alkalosis. In respiratory alkalosis, there is an elevated pH and low carbon dioxide levels (PaCO2 < 35 mmHg). In the given arterial blood gas reading, the patient's pH is 7.41 (within normal range), PaCO2 is 29 mmHg (below normal range), indicating respiratory alkalosis. The bicarbonate level is normal (25 mEq/l), ruling out metabolic acidosis or alkalosis. The low PaO2 (54 mmHg) may indicate hypoxemia, but it is not directly related to the acid-base disorder being assessed. Metabolic acidosis (choice A) is characterized by low pH and low bicarbonate levels, which are not present in this case. Respiratory acidosis (choice B) is indicated by low pH and high PaCO2 levels, which also do not match the provided data. Metabolic alkalosis (choice C) is defined by high pH and high bicarbonate levels, which are not seen in this scenario.

3. When discussing the child's wishes for future care, it is important for the nurse to first identify what the child knows about the disease and his prognosis. Factors such as the perceived severity of the illness will be significant in planning for end-of-life care. If the child does not understand the disease process or prognosis, the plan of care would not be effective or realistic. In addition, asking a child about desired interventions in the event of cardiac or respiratory arrest would not be an appropriate initial area of questioning. If the child does not understand the disease process, these questions may seem frightening or threatening. While exploring the child's belief about death would be important, it would not be the initial area of discussion and should be guided by the child rather than the nurse.

• A. What the child knows about the disease and his prognosis.
• B. How the child would like to handle the plan of care.
• C. What interventions the child would like in the event of cardiac or respiratory arrest.
• D. What the child believes about death.

Correct answer: A

Rationale: When discussing the child's wishes for future care, it is essential to first determine what the child understands about the disease and his prognosis. This information is crucial for planning appropriate end-of-life care. If the child lacks comprehension of the illness and its prognosis, any care plan discussed would be ineffective and unrealistic. Inquiring about desired interventions during cardiac or respiratory arrest is not the initial step, as it may cause distress if the child lacks understanding. While exploring the child's beliefs about death is significant, it should not be the primary focus initially and should be approached based on the child's readiness, not the nurse's agenda. Therefore, the correct first step is to assess what the child knows about the disease and his prognosis.

4. The client develops a tension pneumothorax. Assessment is expected to reveal?

• A. Sudden hypertension and bradycardia
• B. Productive cough with yellow mucus
• C. Tracheal deviation and dyspnea
• D. Sudden development of profuse hemoptysis and weakness

Correct answer: C

Rationale: In a tension pneumothorax, the trachea deviates to the unaffected side due to increased pressure in the affected pleural space, causing respiratory distress. Dyspnea is a hallmark symptom as the lung on the affected side collapses, leading to difficulty in breathing. Sudden hypertension and bradycardia (Choice A) are not typical findings of tension pneumothorax. Productive cough with yellow mucus (Choice B) is more suggestive of respiratory infections rather than a tension pneumothorax. Sudden development of profuse hemoptysis and weakness (Choice D) is not characteristic of tension pneumothorax presentation.

5. Which microorganism is most commonly associated with gastritis?

• A. Syphilis
• B. Cytomegalovirus
• C. H. pylori
• D. Mycobacterium

Correct answer: C

Rationale: H. pylori is the most common microorganism associated with gastritis, present in over 80% of cases. While syphilis, cytomegalovirus, and mycobacterium can also cause gastritis, they are much less prevalent compared to H. pylori. Therefore, the correct answer is H. pylori.
