Nursing Elites

1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. Mr. N is a client who entered the hospital with a diagnosis of diabetic ketoacidosis. The nurse enters his room to check his vital signs and finds him breathing at a rate of 32 times per minute; his respirations are deep and regular. Which type of respiratory pattern is Mr. N most likely exhibiting?

• A. Kussmaul respirations
• B. Cheyne-Stokes respirations
• C. Biot's respirations
• D. Cluster breathing

Correct answer: A

Rationale: Mr. N is most likely exhibiting Kussmaul respirations. Kussmaul respirations are a form of hyperventilation associated with conditions like metabolic acidosis. They are characterized by rapid, regular, and deep breathing. This type of respiratory pattern helps the body compensate for metabolic acidosis by attempting to blow off excess carbon dioxide. This pattern is different from Cheyne-Stokes respirations (choice B), which are characterized by alternating periods of deep, rapid breathing followed by apnea. Biot's respirations (choice C) are characterized by groups of quick, shallow inspirations followed by irregular periods of apnea, and Cluster breathing (choice D) involves clusters of breaths followed by periods of apnea, often seen in patients with brain injury or neurological conditions.

3. You are creating a teaching plan for a patient with newly diagnosed migraine headaches. Which key item should NOT be included in the teaching plan?

• A. Avoid foods that contain tyramine, such as alcohol and aged cheese.
• B. Avoid drugs such as Tagamet, nitroglycerin, and Nifedipine.
• C. Continue taking estrogen as prescribed by your physician.
• D. A potential side effect of medications is rebound headache.

Correct answer: C

Rationale: The correct answer is C: Continue taking estrogen as prescribed by your physician. Medications such as estrogen supplements may actually trigger a migraine headache attack. Fluctuations in estrogen, such as before or during menstrual periods, pregnancy, and menopause, seem to trigger headaches in many women. Choices A and B are important to include in the teaching plan for a patient with migraines as avoiding foods containing tyramine and certain drugs can help prevent migraine triggers. Choice D is also relevant as it is essential for the patient to be aware of potential side effects of medications, including rebound headaches.

4. Select the age group that is coupled with an infectious disease that is most common in this age group.

• A. Infants: High bilirubin
• B. Pre-School and School Age Children: Shingles
• C. Young Adults and Teenagers: Sexually transmitted diseases
• D. The Elderly: Malaria

Correct answer: C

Rationale: Young adults and teenagers are at the highest risk for sexually transmitted diseases due to their sexual activity. High bilirubin is a laboratory finding related to jaundice and not an infectious disease. Shingles is more common in the elderly population, not in pre-school and school-age children. Malaria is not most common in the elderly; it is prevalent in regions with specific mosquito vectors. Therefore, the correct answer is that young adults and teenagers are most commonly associated with sexually transmitted diseases.

5. A patient is being seen in the crisis unit reporting that poison letters are coming in the mail. The patient has no history of psychiatric illness. Which group of the following medications would the patient most likely be started on?

• A. Aripiprazole (Abilify)
• B. Risperidone (Risperdal Consta)
• C. Fluphenazine (Prolixin)
• D. Fluoxetine (Prozac)

Correct answer: A

Rationale: In this scenario, where a patient without a history of psychiatric illness is experiencing psychotic symptoms like believing in poison letters, the most suitable medication group to start the patient on would be atypical antipsychotics. Aripiprazole (Abilify) belongs to this group and is preferred due to its efficacy with fewer side effects compared to conventional antipsychotics. Risperidone (Risperdal Consta) is also an atypical antipsychotic but is usually indicated after stabilizing the patient with oral medications. Fluphenazine (Prolixin) is a conventional antipsychotic, which is less favored due to its side effect profile. Fluoxetine (Prozac) is an antidepressant and is not the first-line treatment for psychotic symptoms.
