Nursing Elites

1. Because of the possible nervous system side-effects that occur with isoniazid (Nydrazid) therapy, which supplementary nutritional agent would the nurse teach the client to take as a prophylaxis?

• A. Alpha tocopherol (vitamin E)
• B. Ascorbic acid (vitamin C)
• C. Calcitriol (vitamin D)
• D. Pyridoxine (vitamin B6)

Correct answer: D

Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.

2. 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.

3. 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.

4. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?

• A. Ca
• B. K
• C. Na
• D. Cl

Correct answer: B

Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.

5. A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?

• A. The patient may be developing CHF
• B. The patient may be having a MI
• C. The patient may be developing COPD
• D. The patient may be having an onset of PVD

Correct answer: B

Rationale: In this scenario, the patient's symptoms of shortness of breath (SOB) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness. Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or peripheral vascular disease (PVD).
