1. A patient in the cardiac unit is concerned about the risk factors associated with atherosclerosis. Which of the following are hereditary risk factors for developing atherosclerosis?

• A. Family history of heart disease
• B. Overweight
• C. Smoking
• D. Age

Correct answer: A

Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.

2. The healthcare professional needs to validate which of the following statements pertaining to an assigned client?

• A. The client has a hard, raised, red lesion on his right hand.
• B. A weight of 185 lbs. is recorded in the chart.
• C. The client reported an infected toe.
• D. The client's blood pressure is 124/70.

Correct answer: C

Rationale: Validation is the process of confirming that data are actual and factual. Data that can be measured can be accepted as factual, as in options 1, 3, and 4. The weight, blood pressure, and physical appearance of a lesion can be objectively verified. However, option C, the client reporting an infected toe, requires the nurse to directly assess the client's toe to confirm the statement. This choice involves subjective data that needs to be validated through direct observation, making it the correct answer. Options A, B, and D provide data that can be measured objectively and verified without the need for further assessment.

3. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

• A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
• B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
• C. The client should lie flat on their back for a specific period following the procedure.
• D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

4. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?

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

Correct answer: A

Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.

5. Mr. Y had surgery two days ago and is recovering on the surgical unit of the hospital. Just before lunch, he develops chest pain and difficulties with breathing. His respiratory rate is 32/minute, his temperature is 100.8�F, and he has rales on auscultation. Which of the following nursing interventions is most appropriate in this situation?

• A. Place the client in the Trendelenburg position
• B. Contact the physician for an order for antibiotics
• C. Administer oxygen therapy
• D. Decrease his IV rate

Correct answer: C

Rationale: Chest pain, dyspnea, tachypnea, mild fever, and rales or crackles on auscultation in a client who had surgery 2 days ago may be indicative of a pulmonary embolism. The nurse should administer oxygen to address his breathing and assist him to a comfortable position to facilitate better oxygenation before contacting the physician. Placing the client in the Trendelenburg position is not recommended in this situation as it may worsen a potential pulmonary embolism by increasing venous return. Contacting the physician for antibiotics is not the priority as the immediate concern is addressing the breathing difficulty. Decreasing the IV rate is not indicated in this situation where the client is experiencing respiratory distress and needs oxygen therapy.
