Nursing Elites

1. What are the side effects of first-generation over-the-counter (OTC) antihistamines like diphenhydramine (Benadryl) and hydroxyzine (Atarax) in infants and children?

• A. Reye's syndrome.
• B. cholinergic effects.
• C. paradoxical CNS stimulation.
• D. nausea and diarrhea.

Correct answer: paradoxical CNS stimulation.

Rationale: The correct answer is paradoxical CNS stimulation. First-generation OTC antihistamines, such as diphenhydramine and hydroxyzine, can lead to paradoxical CNS stimulation in infants and children. This phenomenon is characterized by symptoms like excitement, euphoria, restlessness, and confusion, rather than the expected sedative effect. Due to this unexpected response, these antihistamines are used less frequently in pediatric populations. Reye's syndrome is a rare systemic response to a virus and is not a side effect of antihistamines. First-generation OTC antihistamines do not typically exhibit cholinergic effects. Nausea and diarrhea are uncommon side effects of these antihistamines and are less commonly observed than paradoxical CNS stimulation.

2. The nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?

• A. Hypocalcemia.
• B. Hyponatremia.
• C. Hyperkalemia.
• D. Hypophosphatemia.

Correct answer: Hypocalcemia.

Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.

3. A healthcare professional is reviewing a patient’s current Lithium levels. Which of the following values is outside the therapeutic range?

• A. 1.0 mEq/L
• B. 1.1 mEq/L
• C. 1.2 mEq/L
• D. 1.3 mEq/L

Correct answer: 1.3 mEq/L

Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.

4. While assessing a patient who has undergone a recent CABG, the nurse notices a mole with irregular edges and a bluish color. What should the nurse do next?

• A. Recommend a dermatological consult to the physician.
• B. Note the location of the mole and contact the physician via telephone.
• C. Note the location of the mole and follow-up with the attending physician through the medical record and a phone call.
• D. Remove the mole with a sharp debridement technique, following approval from the charge nurse.

Correct answer: Note the location of the mole and follow-up with the attending physician through the medical record and a phone call.

Rationale: In this scenario, the nurse should note the location of the mole and follow up with the attending physician through the medical record and a phone call. This action is appropriate because a mole with irregular edges and a bluish color raises concern for melanoma, a type of skin cancer. Recommending a dermatological consult (Choice A) might delay the evaluation and management of the mole. Contacting the physician via telephone (Choice B) may not provide a documented record of the observation. Removing the mole without proper evaluation (Choice D) could be dangerous and is not within the nurse's scope of practice.

5. After experiencing a left frontal lobe CVA, a fifty-five-year-old man is being monitored by a nurse. The patient’s family is not present in the room. What should the nurse observe most closely for?

• A. Changes in emotion and behavior
• B. Monitor loss of hearing
• C. Observe appetite and vision deficits
• D. Changes in facial muscle control

Correct answer: Changes in emotion and behavior

Rationale: The correct answer is to watch for changes in emotion and behavior. The frontal lobe, particularly the left side, is responsible for regulating behavior and emotions. Therefore, following a left frontal lobe CVA, monitoring for alterations in emotion and behavior is crucial. Choices B, C, and D are incorrect because loss of hearing, appetite and vision deficits, and changes in facial muscle control are not directly associated with a left frontal lobe CVA.
