NCLEX PN Exam Cram
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. Support systems during the grieving process include all of the following except:
- A. a despondent friend.
- B. a nurse.
- C. a social worker.
- D. a family member.
Correct answer: B
Rationale: During the grieving process, it is essential to have a support system in place. Options B, C, and D - a nurse, a social worker, and a family member, respectively, are individuals who can provide comfort, guidance, and practical assistance to someone who is grieving. However, a despondent friend, as stated in the question, is not an ideal choice for support during this period. A despondent friend is someone who is feeling extremely unhappy and discouraged, and may not have the emotional capacity to provide the needed support to a grieving individual. It is important for someone who is grieving to have support from individuals who can offer understanding, empathy, and strength, which a despondent friend may struggle to provide.
3. When teaching a patient with COPD pulmonary exercises, what should be done?
- A. Teach pursed-lip breathing techniques.
- B. Encourage repetitive heavy lifting exercises to increase strength.
- C. Limit exercises due to respiratory acidosis.
- D. Take breaks every 10-20 minutes during exercises.
Correct answer: A
Rationale: The correct answer is to teach pursed-lip breathing techniques. Pursed-lip breathing helps to decrease the volume of air expelled by keeping the airways open longer, making it easier for patients with COPD to breathe out. Encouraging heavy lifting exercises (Choice B) is not suitable for patients with COPD as it can lead to increased shortness of breath. Limiting exercises due to respiratory acidosis (Choice C) is not correct; instead, exercises should be tailored to the patient's tolerance. Taking breaks every 10-20 minutes (Choice D) is not specific to the management of COPD pulmonary exercises.
4. 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.
5. 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.
