1. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:
- A. a maintenance dose.
- B. a loading dose.
- C. a medication with no first-pass effect.
- D. the medication to be given intravenously.
Correct answer: B
Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.
2. A homeless person has been admitted to the medical unit and placed on airborne precautions for suspected active TB infection. The nurse will assess for these signs and symptoms (Select one that doesn't apply).
- A. Weight gain
- B. Fatigue
- C. Bloody sputum
- D. Diaphoresis during sleep
Correct answer: A
Rationale: The correct answer is 'Weight gain.' When assessing for signs and symptoms of active TB infection, weight loss is typically observed rather than weight gain. Other common signs and symptoms include fatigue, bloody sputum, and diaphoresis during sleep. Fatigue, bloody sputum, and diaphoresis during sleep are all associated with active TB infection. Weight gain is not typically seen in active TB; instead, patients usually experience weight loss due to the impact of the infection on their overall health.
3. A female client complains to the nurse at the health department that she has fatigue, shortness of breath, and lightheadedness. Her history reveals no significant medical problems. She states that she is always on a fad diet without any vitamin supplements. Which tests should the nurse expect the client to have first?
- A. peptic ulcer studies
- B. complete blood count, including hematocrit and hemoglobin
- C. genetic testing
- D. hemoglobin electrophoresis
Correct answer: B
Rationale: The correct answer is to perform a complete blood count, including hematocrit and hemoglobin, as the initial tests to assess the client's symptoms related to fatigue, shortness of breath, and lightheadedness. These symptoms can be indicative of anemia, which can be caused by nutritional deficiencies due to fad dieting without vitamin supplements. Peptic ulcer studies, genetic testing, and hemoglobin electrophoresis are not the most appropriate initial tests for the client's presenting symptoms and history. Peptic ulcer studies are not relevant to the client's symptoms. Genetic testing is not indicated based on the client's presentation and history. Hemoglobin electrophoresis is used to diagnose specific types of anemia and is not the first-line test in this scenario. Further testing decisions should be based on the results of the initial tests, the client's history, and other relevant factors.
4. During a petit mal seizure in the clinic, what should be the highest priority?
- A. Provide a safe environment free of obstructions in the immediate area
- B. Call a code
- C. Contact the patient's physician
- D. Prevent excessive movement of the extremities
Correct answer: A
Rationale: During a petit mal seizure, the highest priority is to provide a safe environment free of obstructions in the immediate area. This action aims to prevent injuries to the patient during the seizure. While calling a code or contacting the patient's physician may be necessary at some point, immediate safety measures take precedence. Preventing excessive movement of the extremities is relevant but ensuring a safe environment is crucial to avoid harm during the seizure.
5. A newborn baby exhibits a reflex that includes hand opening, abducted, and extended extremities following a jarring motion. Which of the following correctly identifies the reflex?
- A. ATNR reflex
- B. Startle reflex
- C. Grasping reflex
- D. Moro reflex
Correct answer: D
Rationale: The Moro reflex, also known as the startle reflex, is the correct answer. This reflex is characterized by the baby's response to a sudden head movement or loud noise, causing them to open their hands, extend their arms, and then bring them back towards their body. The characteristics mentioned in the question - hand opening, abducted, and extended extremities following a jarring motion - align with the Moro reflex. The asymmetrical tonic neck reflex (ATNR) involves the head turning to one side with extension of the same side's arm and leg, not the described characteristics. The grasping reflex involves the baby's response to touch on the palm, causing them to grasp an object. While the Moro reflex is often referred to as the startle reflex due to its response to sudden stimuli, the specific characteristics described in the question match the Moro reflex.
