1. Which bioterrorism agent is at high risk for use as a potential biological weapon that is readily transmitted by several portals of entry?

• A. anthrax
• B. smallpox
• C. botulism
• D. tularemia

Correct answer: A

Rationale: Anthrax is the correct answer. Anthrax spores can be transmitted through inhalation, ingestion, or skin contact, making it a high-risk agent for bioterrorism. Smallpox, botulism, and tularemia are also potential bioterrorism agents, but they do not have the same versatility in terms of multiple portals of entry, unlike anthrax.

2. The nurse is assessing a client with pneumonia who is receiving oxygen therapy. Which finding indicates that the therapy is effective?

• A. The client's respiratory rate is 20 breaths per minute.
• B. The client's arterial blood gases show a pH of 7.35.
• C. The client's oxygen saturation is 92%.
• D. The client's breath sounds are clear.

Correct answer: A

Rationale: A respiratory rate of 20 breaths per minute indicates effective oxygen therapy. In pneumonia, the respiratory rate typically increases due to the body's effort to improve oxygenation. Option B (pH of 7.35) is related to acid-base balance, not specifically indicating oxygen therapy effectiveness. Option C (oxygen saturation of 92%) is below the normal range (95-100%), suggesting the need for oxygen therapy. Option D (clear breath sounds) is a positive finding but not a direct indicator of oxygen therapy effectiveness.

3. The healthcare provider is preparing to administer digoxin (Lanoxin) to a client. Which assessment finding should the healthcare provider report before administering the medication?

• A. Apical pulse of 58 beats per minute.
• B. Serum potassium level of 3.0 mEq/L.
• C. Blood pressure of 140/90 mm Hg.
• D. Client reports seeing halos around lights.

Correct answer: D

Rationale: Seeing halos around lights is a classic symptom of digoxin toxicity, known as visual disturbances. This finding indicates an adverse effect of digoxin and should be reported immediately to the healthcare provider. Monitoring for visual changes is crucial as it can progress to more severe toxicity, leading to life-threatening dysrhythmias or other complications. Apical pulse, serum potassium level, and blood pressure are important assessments when administering digoxin, but the presence of visual disturbances, such as seeing halos around lights, takes precedence due to its direct association with digoxin toxicity. Changes in these other parameters should also be noted and addressed, but they are not the priority when compared to a symptom directly linked to potential toxicity.

4. The healthcare provider is assessing a client with a suspected pulmonary embolism. Which finding requires immediate intervention?

• A. Chest pain.
• B. Shortness of breath.
• C. Tachycardia.
• D. Cyanosis.

Correct answer: D

Rationale: Cyanosis is a late sign of hypoxemia and indicates severe oxygen deprivation, necessitating immediate intervention in a client with a suspected pulmonary embolism. Chest pain, shortness of breath, and tachycardia are also concerning symptoms in pulmonary embolism; however, cyanosis signifies critical oxygen deficiency and warrants urgent attention to prevent further complications.

5. Which annual screening should the nurse include when planning eye health programs at a preschool?

• A. visual acuity
• B. red light reflex
• C. conjunctivitis
• D. glaucoma

Correct answer: A

Rationale: The correct answer is A: visual acuity. Screening for visual acuity is essential in preschoolers to identify any vision issues early on, such as nearsightedness or farsightedness, which may require corrective lenses or other interventions. Red light reflex (choice B) is a method used to assess the eyes for abnormalities, but it is not typically included in routine preschool eye health screenings. Conjunctivitis (choice C) is an eye infection and not a screening test. Glaucoma (choice D) is a condition more commonly associated with adults and the elderly, making it less relevant for preschool eye health programs.
