Nursing Elites

1. A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?

• A. Depressed function of the CNS
• B. Increased blood flow
• C. Decreased venous capacity
• D. Pain relief

Correct answer: C

Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.

2. What happens if folic acid is administered to treat anemia without determining its underlying cause?

• A. Erythropoiesis is inhibited
• B. Excessive levels of folic acid might accumulate, causing toxicity
• C. The symptoms of pernicious anemia might be masked, delaying treatment
• D. Intrinsic factor is destroyed

Correct answer: C

Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.

3. A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:

• A. urinary excess
• B. hyperpituitarism
• C. urinary deficit
• D. hyperthyroidism

Correct answer: C

Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output. Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.

4. A patient 3 hours post-op from a hysterectomy is complaining of intense pain at the incision site. When assessing the patient, the nurse notes a BP of 169/93, pulse 145 bpm, and regular. What action should the nurse take?

• A. Reassure the patient that pain is normal following surgery.
• B. Administer prn Nifedipine and assess the client's response.
• C. Administer prn Meperidine HCL and assess the client's response.
• D. Recheck BP and pulse rate every 20 minutes for the next hour.

Correct answer: C

Rationale: The correct action for the nurse to take in this situation is to administer prn Meperidine HCL and assess the client's response. A BP of 169/93 and a pulse of 145 bpm indicate pain-related hypertension and sinus tachycardia, which are physiological responses to pain. Treating the cause of the increased pulse rate requires pain medication. Reassuring the patient about normal post-surgery pain is important, but addressing the physiological responses to pain is a priority. Administering Nifedipine, a calcium channel blocker, is not indicated for pain management but for hypertension. Rechecking the BP and pulse rate without addressing the pain directly does not address the underlying issue causing the elevated vital signs.

5. A client arrives in the emergency department after severely lacerating the left hand with a knife. HR 96, BP 150/88, R36. The client is extremely anxious and crying uncontrollably. Based on this assessment, the nurse anticipates that this client would be in which acid-base imbalance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is respiratory alkalosis. Hyperventilation due to anxiety, pain, shock, severe infection, fever, or liver failure can lead to respiratory alkalosis. In this scenario, the client is extremely anxious and crying uncontrollably, indicating an increased respiratory rate and CO2 loss. Respiratory acidosis (choice A) is incorrect as it is characterized by an increase in CO2 levels, not a loss. Metabolic acidosis (choice C) involves a decrease in blood pH due to an accumulation of acids or loss of bicarbonate, which is not the case here. Metabolic alkalosis (choice D) results from excess bicarbonate or a loss of acids, not from increased CO2 loss due to hyperventilation.
