Nursing Elites

1. The schizophrenic client who is admitted to the hospital for possible bowel obstruction has an NG tube and complains of pain. What should the nurse do at this time?

• A. Decrease the stimuli and observe frequently
• B. Administer the PRN sedative
• C. Call the physician immediately
• D. Administer the PRN pain medication

Correct answer: D

Rationale: In this scenario, the nurse should administer the PRN (as needed) pain medication to address the schizophrenic client's complaint of pain. It is essential to provide relief and comfort to the client experiencing pain. Option A, decreasing stimuli and observing frequently, may not address the underlying cause of pain and delay relief. Option B, administering a sedative, does not target the pain but may mask symptoms. Option C, calling the physician immediately, while important in some situations, is not the most immediate action needed to alleviate the client's pain. Therefore, the most appropriate action at this time is to administer the PRN pain medication to help alleviate the client's discomfort.

2. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

• A. metoclopramide (Reglan)
• B. ondansetron (Zofran)
• C. hydroxyzine (Vistaril)
• D. prochlorperazine (Compazine)

Correct answer: B

Rationale: Zofran is a serotonin antagonist that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.

3. A nurse is teaching a client newly diagnosed with Emphysema about the disease process. Which of the following statements best explains the problems associated with emphysema and could be adapted for use in the nurse's discussion with the client?

• A. Hyperactivity of the medium-sized bronchi caused by an inflammatory response leads to wheezing and tightness in the chest.
• B. Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.
• C. Vasodilation, congestion, and mucosal edema cause a chronic cough and sputum production.
• D. Chloride is not being transported properly, producing excess absorption of water and sodium, and thick viscous mucus

Correct answer: B

Rationale: The correct answer is: 'Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.' Emphysema is a breakdown of the elastin and fiber network of the alveoli where the alveoli enlarge or the walls are destroyed. This alveolar destruction leads to the formation of larger-than-normal air spaces. Emphysema is one of a group of pulmonary diseases of a chronic nature characterized by increased resistance to airflow; the entity is part of chronic obstructive pulmonary disease (COPD). Choice A is incorrect because emphysema is not primarily characterized by hyperactivity of the medium-sized bronchi causing wheezing and tightness in the chest. Choice C is incorrect because vasodilation, congestion, and mucosal edema are not the primary mechanisms involved in emphysema, and they do not directly lead to chronic cough and sputum production. Choice D is incorrect because emphysema is not related to chloride transport issues and thick viscous mucus production.

4. A pregnant Asian client who is experiencing morning sickness wants to take ginger to relieve the nausea. Which of the following responses by the nurse is appropriate?

• A. "I will call your physician to see if we can start some ginger."?
• B. "We don't use home remedies in this clinic."?
• C. "Herbs are not as effective as regular medicines."?
• D. "Just eat some dry crackers instead."?

Correct answer: A

Rationale: The correct response is to offer to consult with the physician regarding the use of ginger, showing cultural sensitivity. Ginger is known to help relieve nausea, especially in pregnancy. Choice A is the correct answer as it respects the client's preference for a home remedy and involves the physician in the decision-making process. Choice B dismisses the client's preference for a home remedy without exploring its potential benefits. Choice C makes a generalized statement discrediting the effectiveness of herbs, which is not evidence-based and disregards the client's beliefs. Choice D offers an alternative without addressing the client's specific request, failing to acknowledge the client's autonomy and cultural background.

5. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?

• A. metabolic alkalosis
• B. homeostasis
• C. respiratory acidosis
• D. respiratory alkalosis

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.
