1. Which type of Leukocyte is involved with allergic responses and the destruction of parasitic worms?

• A. Neutrophils
• B. Lymphocytes
• C. Eosinophils
• D. Monocytes

Correct answer: C

Rationale: Eosinophils are the correct answer. Eosinophils are specialized white blood cells that play a crucial role in allergic responses and combating parasitic infections. They release substances to destroy parasites and modulate allergic reactions. Neutrophils (Choice A) are mainly involved in fighting bacterial infections. Lymphocytes (Choice B) play a key role in the immune response, including antibody production, but are not primarily responsible for combating parasites or allergic responses. Monocytes (Choice D) are involved in immune defense, differentiating into macrophages or dendritic cells, but they are not mainly associated with allergic responses or parasitic worm destruction.

2. A mother brings her child, who has a history of asthma, to the emergency room. The child is wheezing and speaking one word between each breath. The child is anxious, tachycardic, and has labored respirations. Which assessment is most important for the nurse to obtain?

• A. Type of inhaler the child typically uses on a regular basis
• B. Frequency of rescue inhaler use during the week
• C. Last dose and type of rescue inhaler used by the child
• D. Type of allergen exposure or trigger for the current episode

Correct answer: C

Rationale: The correct answer is C because knowing the last dose and type of rescue inhaler used helps assess if the child has received adequate treatment and if further intervention is needed. This information is crucial in managing an acute asthma exacerbation. Choice A, the type of inhaler the child typically uses, is less critical during an emergency. Choice B, the frequency of rescue inhaler use during the week, is important for general asthma management but does not provide immediate guidance in the acute situation. Choice D, the type of allergen exposure or trigger, is more relevant for preventive strategies and does not directly impact the immediate treatment of the child's acute asthma attack.

3. When administering ceftriaxone sodium intravenously to a client before surgery, which assessment finding requires the most immediate intervention by the nurse?

• A. Headache
• B. Pruritus
• C. Nausea
• D. Stridor

Correct answer: D

Rationale: Stridor is a high-pitched, noisy breathing sound that can indicate a serious condition like airway obstruction or a severe allergic reaction, necessitating immediate intervention to maintain the client's airway and prevent further complications. While headache, pruritus, and nausea are important to assess and manage, they are not as immediately life-threatening as stridor, which requires prompt attention to prevent respiratory compromise.

4. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?

• A. 18
• B. 27
• C. 36
• D. 45

Correct answer: D

Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.

5. The client with a mechanical valve replacement understands the discharge teaching when the client makes which statement?

• A. ''I will need to take antibiotics before any type of invasive dental work''
• B. ''I will not have to take any more heart medication since I have a new valve''
• C. ''I will need to have this valve replaced in about 10 years''
• D. ''I should notify my healthcare provider if I hear a clicking sound near my heart''

Correct answer: A

Rationale: The correct answer is A. Clients with mechanical valve replacements need to take prophylactic antibiotics before dental procedures to prevent endocarditis. Choice B is incorrect because even with a new valve, heart medications may still be necessary to manage the condition. Choice C is incorrect because mechanical valves typically do not need replacement as frequently as within 10 years. Choice D is incorrect because hearing a clicking sound near the heart could indicate valve malfunction, not just the need to notify the healthcare provider.
