Basic Principles of Patient Care Questions
Question 1 of 5
Which of the following tests MOST reliably predicts the likelihood that a patient will develop malignant hyperthermia?
Correct Answer: C
Rationale: The caffeine-halothane contracture test is the gold standard for diagnosing susceptibility to malignant hyperthermia, as it directly assesses muscle response to triggering agents.
Question 2 of 5
The nurse is caring for a postoperative patient on the medical-surgical floor. Which activity will the nurse encourage to prevent venous stasis and the formation of thrombus?
Correct Answer: C
Rationale: Correct Answer: C (Leg exercises) Rationale: 1. Leg exercises promote muscle contractions, aiding in venous return. 2. Movement prevents stasis and thrombus formation. 3. Diaphragmatic breathing, incentive spirometry, and coughing are important postoperative activities but do not directly prevent venous stasis like leg exercises do.
Question 3 of 5
The nurse is caring for a patient who will undergo a removal of a lung lobe. Which level of care will the patient require immediately post procedure?
Correct Answer: B
Rationale: The correct answer is B: Acute care - intensive care unit. Post lung lobe removal, the patient may require close monitoring of vital signs, respiratory status, pain management, and potential complications like bleeding or respiratory distress. The intensive care unit provides specialized care and continuous monitoring by healthcare professionals to manage any postoperative complications promptly. Choice A (Acute care - medical-surgical unit) may not provide the level of monitoring and specialized care that an intensive care unit offers for a patient undergoing major surgery like lung lobe removal. Choices C (Ambulatory surgery) and D (Ambulatory surgery - extended stay) are not appropriate postoperative care settings for a patient undergoing lung lobe removal, as this surgery is major and requires more intensive monitoring and care than what ambulatory surgery settings can provide.
Question 4 of 5
Your adult patient sustained a right index finger amputation at work. On arrival, first responders have the bleeding controlled with sterile dressings, and the patient is conscious, alert, and oriented. What is the best way to manage the patient's amputated finger during transport to the hospital?
Correct Answer: B
Rationale: The correct answer is B: Wrap the finger in gauze (moistened with normal saline), and seal the finger in a plastic bag before placing it on ice. This method helps preserve the amputated part by keeping it moist and cool, which can improve the chances of successful reattachment. Here's a step-by-step rationale: 1. Moistening the gauze with normal saline helps prevent the tissue from drying out, maintaining its viability. 2. Sealing the finger in a plastic bag helps protect it from contamination and further damage during transport. 3. Placing the sealed finger on ice helps keep it cool, which slows down metabolic processes and reduces tissue damage. 4. Avoiding direct contact of the finger with ice prevents frostbite and tissue damage from extreme cold. In summary, option B is the best choice as it optimally preserves the amputated finger for potential reattachment. Option A does not maintain moisture, leading to tissue damage. Option C's use of water
Question 5 of 5
Which of the following operational modes used in EMS communication can transmit voice as well as telemetry simultaneously?
Correct Answer: B
Rationale: The correct answer is B: Multiplex mode. In multiplex mode, voice and telemetry signals are combined and transmitted simultaneously on a single communication channel. This mode allows for efficient use of bandwidth by transmitting multiple types of data concurrently. Trunk system mode (A) involves multiple channels for different users, not for voice and telemetry together. Duplex mode (C) allows for two-way communication but not necessarily simultaneous voice and telemetry. Simplex mode (D) only allows communication in one direction at a time, not suitable for transmitting voice and telemetry simultaneously.
