Question 1 of 5
After a severe auto accident, a patient has been taken to the trauma unit and has an estimated
Correct Answer: D
Rationale: Packed red blood cells contain primarily red blood cells and are used to increase the patient's oxygen-carrying capacity. After a severe auto accident, the patient may experience blood loss and require a transfusion of packed red blood cells to improve oxygen delivery to tissues and organs. While other blood products like whole blood or fresh frozen plasma contain additional components (such as plasma proteins or clotting factors), packed red blood cells are specifically indicated to address oxygen-carrying needs in cases of significant blood loss or anemia. Therefore, in the trauma unit for a patient following a severe auto accident, the nurse should prepare to administer packed red blood cells.
Question 2 of 5
The client is receiving a very expensive medication. The client asks the nurse why the medicine is so expensive. What is the best response by the nurse?
Correct Answer: C
Rationale: High drug costs stem from research, development, and production expenses-years of trials and manufacturing-requiring companies to recover investments, a factual explanation. Insurance coverage sidesteps the question. Advertising adds cost but isn't primary. Accountability is opinion, not answer. Development costs provide a clear, neutral reason, educating the client on pharmaceutical economics.
Question 3 of 5
A client is prescribed ciprofloxacin (Cipro) for a urinary tract infection. Which instruction should the nurse include?
Correct Answer: B
Rationale: Ciprofloxacin, a fluoroquinolone, treats UTIs but causes photosensitivity, risking severe sunburn. Avoiding sun exposure prevents this, a key instruction for safety. Milk reduces absorption via calcium binding, lowering efficacy. Taking it PRN risks incomplete treatment and resistance. Doubling doses courts toxicity. Sun avoidance aligns with ciprofloxacin's side effect profile, critical for outpatient adherence where sun exposure is common. This teaching prevents avoidable harm, distinguishing it from administration errors, making B the essential instruction.
Question 4 of 5
Glyceryl trinitrate for angina is most effective when given:
Correct Answer: C
Rationale: Glyceryl trinitrate, also known as nitroglycerin, is a medication commonly used for the management of angina (chest pain). When administered sublingually (under the tongue), glyceryl trinitrate is rapidly absorbed through the highly vascular sublingual mucosa, leading to a quick onset of action. The sublingual route allows for the drug to enter the bloodstream directly without being metabolized by the liver first, resulting in faster relief of angina symptoms. This makes sublingual administration the most effective route for managing acute episodes of angina. Other routes of administration, such as oral, subcutaneous, intravenous, or intramuscular, would not provide the same rapid and reliable relief for angina.
Question 5 of 5
Albuterol can be given in all but which of these forms:
Correct Answer: A
Rationale: Albuterol is typically administered through inhalation as an aerosol or nebulized solution to provide quick relief of bronchospasm in conditions such as asthma or chronic obstructive pulmonary disease. It can also be administered intravenously in emergency situations for severe bronchospasm or anaphylaxis. Albuterol is not formulated as an extended-release oral medication due to the need for rapid onset of action in managing acute bronchospasm.
