Nursing Elites

1. A client is admitted with the diagnosis of pulmonary embolism. While taking a history, the client tells the nurse he was admitted for the same thing twice before, the last time just 3 months ago. The nurse would anticipate the healthcare provider ordering:

• A. Pulmonary embolectomy
• B. Vena caval interruption
• C. Increasing the coumadin therapy to achieve an INR of 3-4
• D. Thrombolytic therapy

Correct answer: B

Rationale: In the case of a client with a history of recurrent pulmonary embolism or contraindications to heparin, vena caval interruption may be necessary. Vena caval interruption involves placing a filter device in the inferior vena cava to prevent clots from traveling to the pulmonary circulation. Pulmonary embolectomy is a surgical procedure to remove a clot from the pulmonary artery, which is usually considered in severe or life-threatening cases. Increasing coumadin therapy to achieve a higher INR may be an option but vena caval interruption would be more appropriate in this scenario. Thrombolytic therapy is used in acute cases of pulmonary embolism to dissolve the clot rapidly, but in a recurrent case with contraindications to anticoagulants, vena caval interruption would be a preferred intervention.

2. A client in labor has an electronic fetal monitor attached to the abdomen, and the nurse notes that the baby's heart rate slows down during each contraction, returning to normal limits only after the contraction is complete. Which 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 refer to a pattern where the baby's heart rate decreases during contractions and does not return to normal until after the contraction ends. This is considered a non-reassuring sign as it indicates potential fetal distress. Late decelerations are associated with uteroplacental insufficiency, and immediate medical attention is required. Variable decelerations (Choice A) are abrupt, unpredictable decreases in the fetal heart rate, usually associated with cord compression. Early decelerations (Choice C) are usually benign and mirror the contraction pattern. Accelerations (Choice D) are reassuring signs of fetal well-being, characterized by an increase in the fetal heart rate.

3. Which of the following conditions may warrant a serum creatinine level?

• A. Rhabdomyolysis
• B. Digitalis toxicity
• C. Glomerulonephritis
• D. All answers are correct

Correct answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.

4. In which of the following examples would informed consent not be required?

• A. A patient is apprehensive about an upcoming surgery and chooses not to learn of the risks involved with the procedure.
• B. A child is rushed to the Emergency Room after falling from a third-story window.
• C. An adult in a coma in a mental health institution with no listed next of kin.
• D. Informed consent is not required in any of the above examples.

Correct answer: D

Rationale: In emergency situations where immediate treatment is necessary to prevent further harm or save a life, such as in option B where a child is rushed to the Emergency Room after a fall, informed consent may be waived to provide prompt care. In option A, though the patient is apprehensive about surgery and chooses not to learn the risks, informed consent is not required as it is the patient's right to refuse information. In option C, when an adult is in a coma with no next of kin listed, decisions may be made in the patient's best interest following legal and ethical guidelines. Therefore, informed consent is not needed in any of the scenarios presented.

5. 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.
