Nursing Elites

1. Following the administration of her annual influenza vaccination, a health care worker remains at the clinic for observation due to pain at the injection site. What should the nurse recommend?

• A. ASA
• B. Acetaminophen
• C. Meperidine (Demerol)
• D. Heat application

Correct answer: B

Rationale: The correct recommendation for pain at the injection site after an influenza vaccination is Acetaminophen. Acetaminophen is a suitable choice for managing mild to moderate pain and fever commonly associated with vaccinations. Choice A, ASA (aspirin), is not recommended due to the risk of Reye's syndrome in children and teenagers following viral illnesses. Choice C, Meperidine (Demerol), is a potent opioid analgesic and is not typically indicated for mild pain relief. Choice D, heat application, is not the standard recommendation for pain at an injection site and may not provide adequate relief.

2. A tension pneumothorax requires a needle thoracostomy and/or chest tube placement as treatment to which component of the pathophysiology of the condition?

• A. An accumulation of blood in the pleural space, which makes it difficult for the lungs to exchange gases.
• B. Extreme pain caused by a fractured rib
• C. A large accumulation of trapped air in the pleural space affecting both the lungs and heart.
• D. Sudden failure of the respiratory system due to fluid accumulation in the alveoli

Correct answer: C

Rationale: A tension pneumothorax is characterized by a large accumulation of trapped air in the pleural space, creating pressure that affects both the lungs and heart. This condition can lead to life-threatening consequences by shifting mediastinal structures and impairing cardiac function. Treatment involves decompressing the trapped air to relieve the tension. Choices A, B, and D are incorrect as they do not describe the primary pathophysiological mechanism of tension pneumothorax, which is the accumulation of air in the pleural space, not blood, rib fractures, or alveolar fluid accumulation.

3. Which immunoglobulin presents the first challenge to the antigen?

• A. IgA
• B. IgG
• C. IgM
• D. IgE

Correct answer: C

Rationale: IgM is the first immunoglobulin to challenge the antigen during an immune response. IgM is the primary antibody produced during the initial or primary immune response. It is efficient in agglutination and complement activation, making it crucial in the early stages of defense. IgA is mainly found in mucosal areas and secretions. IgG is the most abundant antibody in circulation and is involved in secondary immune responses. IgE is primarily associated with allergic reactions and parasitic infections. Therefore, IgM is the correct choice as it acts first during the immune response, while the other immunoglobulins have different roles and functions.

4. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What critical contraindication should the nurse review with the patient?

• A. Use of nitrates
• B. Use of antihypertensive medications
• C. History of hypertension
• D. History of peptic ulcer disease

Correct answer: A

Rationale: The correct answer is A: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, which can lead to a dangerous drop in blood pressure. Choice B (Use of antihypertensive medications) is incorrect because antihypertensive medications are not a critical contraindication for sildenafil use. Choice C (History of hypertension) is incorrect as it is not a contraindication for sildenafil; in fact, sildenafil is sometimes used in patients with hypertension. Choice D (History of peptic ulcer disease) is also incorrect as it is not a critical contraindication for sildenafil use.

5. What should the nurse include in patient education regarding the effectiveness of oral contraceptives?

• A. Oral contraceptives are highly effective when taken correctly but not 100% foolproof.
• B. Oral contraceptives may take some time to reach full effectiveness after starting.
• C. Oral contraceptives can be less effective if taken with certain antibiotics.
• D. Taking oral contraceptives with food does not significantly affect their efficacy.

Correct answer: C

Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics due to potential drug interactions that may reduce contraceptive efficacy. It is crucial for patients to be aware of this to consider additional contraceptive measures when prescribed antibiotics. Choice A is incorrect because while oral contraceptives are highly effective when taken correctly, they are not 100% foolproof. Choice B is incorrect as oral contraceptives may take some time to reach their full effectiveness after starting. Choice D is also incorrect as taking oral contraceptives with food does not significantly affect their efficacy.
