A client has started sweating profusely due to intense heat. His overall
luid volume is low and he has developed electrolyte imbalance. This
client is most likely suffering from:
- A. Malignant hyperthermia
- B. Heat exhaustion
- C. Heat stroke
- D. Heat cramps
Correct Answer: B
Rationale: Heat exhaustion occurs when a person has enough
diaphoresis that he becomes dehydrated. Intense sweating can cause
both luid and electrolyte imbalances. Untreated heat exhaustion can
lead to heat stroke, which results in organ damage, loss of
consciousness, or death.

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.
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.
Mrs. G is seen for follow-up after testing for chronically high blood glucose levels. Her physician diagnoses her with type 1 diabetes. Which of the following information is part of this client's education about this condition?
- A. Type 1 diabetes occurs due to increased carbohydrate intake and lack of exercise
- B. Type 1 diabetes is managed through diet and exercise
- C. Type 1 diabetes is caused by destruction of beta cells in the pancreas
- D. Type 1 diabetes leads to the body's cells rejecting insulin
Correct Answer: C
Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.
Which of the following interventions is necessary before insertion of an arterial line into the radial artery?
- A. Ensure that the client does not need surgery
- B. Assess the client's grip strength
- C. Perform an Allen test
- D. Check a serum potassium level
Correct Answer: C
Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line.
Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.
Which of the following is a true statement about assessing blood pressure by palpation?
- A. Only the diastolic blood pressure can be assessed through palpation.
- B. The palpation technique is most useful for infants and small children.
- C. Hypertension is a common condition that might need to be assessed through blood pressure palpation.
- D. Only the systolic blood pressure can be assessed through palpation.
Correct Answer: D
Rationale: When assessing blood pressure by palpation, it is important to note that only the systolic blood pressure can be determined accurately using this method. Diastolic blood pressure cannot be reliably assessed through palpation. The palpation technique is particularly useful in situations where traditional blood pressure measurement methods are challenging, such as in infants, small children, or individuals with low blood pressure that is difficult to hear. Hypertension, a common condition characterized by elevated blood pressure, is typically assessed using auscultation rather than palpation. Therefore, the correct statement is that only the systolic blood pressure can be assessed through palpation.
