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. Which of the following conditions may cause an increased respiratory rate?

• A. Stooped posture
• B. Narcotic analgesics
• C. Injury to the brain stem
• D. Anemia

Correct answer: D

Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen. Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.

3. Your patient has been diagnosed with a left ankle sprain. On the discharge instructions, the physician has prescribed the RICE protocol. This acronym stands for:

• A. Rest, Ice, Compression, Elevation
• B. Radiology, Ice, Compression, Elevation
• C. Rest, Ice, Cast, Elevation
• D. Radiology, Ice, Cast, Elevation

Correct answer: A

Rationale: The correct answer is Rest, Ice, Compression, Elevation. This acronym, RICE, is commonly used for the treatment of injuries like an ankle sprain. Rest allows the injured area to heal, Ice helps reduce swelling and pain (20 minutes on each hour while awake), Compression is usually achieved with an elastic bandage to minimize swelling, and Elevation of the foot above the level of the heart assists in reducing swelling and promoting healing. Choices B, C, and D are incorrect because they include irrelevant terms like Radiology and Cast, which are not part of the standard treatment protocol for an ankle sprain.

4. While caring for a client in labor, a nurse attaches an electronic fetal monitor to the client's abdomen to assess the baby's heart rate. The nurse observes that the baby's heart rate slows down during each contraction and does not return to normal limits until after the contraction is complete. What type of fetal heart rate change does this pattern describe?

• A. Variable decelerations
• B. Late decelerations
• C. Early decelerations
• D. Accelerations

Correct answer: B

Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.

5. At a community health fair, the blood pressure of a 62-year-old client is 160/96 mmHg. The client states, "My blood pressure is usually much lower."? The nurse should tell the client to:

• A. Go get a blood pressure check within the next 15 minutes
• B. Check blood pressure again in two (2) months
• C. See the healthcare provider immediately
• D. Visit the healthcare provider within one (1) week for a BP check

Correct answer: A

Rationale: The blood pressure reading of 160/96 mmHg is moderately high, indicating hypertension. Given that the client mentions their blood pressure is usually lower, there is concern for acute complications like a stroke. Therefore, an immediate reassessment of the blood pressure within the next 15 minutes is warranted to confirm the reading and take appropriate actions if necessary. Waiting for two months (Choice B) or a week (Choice D) could pose risks of delaying intervention. Seeing the healthcare provider immediately (Choice C) is a good option, but in this case, the urgency is not as high as to require immediate attention at the healthcare provider's office.
