1. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

2. A patient with no known allergies is to receive penicillin every 6 hours. When administering the medication, the nurse observes a fine rash on the patient’s skin. The most appropriate nursing action would be to:

• A. Withhold the medication and notify the physician
• B. Administer the medication and notify the physician
• C. Administer the medication with an antihistamine
• D. Apply corn starch soaks to the rash

Correct answer: A

Rationale: In this scenario, the appearance of a rash after administering penicillin, even in a patient with no known allergies, is concerning for a potential allergic reaction. The appropriate action for the nurse to take is to withhold the medication and notify the physician. This precaution is necessary to prevent further administration of a medication that may be causing an adverse reaction, as allergic reactions can range from mild to severe and require immediate intervention.

3. Which of the following conditions may necessitate fluid restriction?

• A. Fever
• B. Chronic Obstructive Pulmonary Disease
• C. Renal Failure
• D. Dehydration

Correct answer: C

Rationale: Renal failure often necessitates fluid restriction to prevent fluid overload. In renal failure, the kidneys are unable to effectively filter and excrete excess fluids, leading to fluid accumulation in the body. Restricting fluid intake helps manage this condition by preventing further fluid buildup and complications such as edema and electrolyte imbalances.

4. A group of clients are being educated about influenza. Which of the following client statements indicates an understanding of the teaching?

• A. ''I should wash my hands after blowing my nose to prevent spreading the virus.''
• B. ''I need to avoid drinking fluids if I develop symptoms.''
• C. ''I need a flu shot every 2 years because of the different flu strains.''
• D. ''I should cover my mouth with my hand when I sneeze.''

Correct answer: A

Rationale: The correct answer is, 'I should wash my hands after blowing my nose to prevent spreading the virus.' This statement shows understanding of the importance of hand hygiene in preventing the spread of influenza. Washing hands after activities like blowing the nose can help reduce the risk of transmitting the virus to others. Choices B, C, and D are incorrect as they do not reflect accurate understanding of influenza prevention measures.

5. Which of the following is not a cause of tachycardia?

• A. Fever
• B. Exercise
• C. Sympathetic nervous system stimulation
• D. Parasympathetic nervous system stimulation

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.
