1. Thrombolytic therapy is frequently used in the treatment of suspected stroke. Which of the following is a significant complication associated with thrombolytic therapy?

• A. Air embolism.
• B. Cerebral hemorrhage.
• C. Expansion of the clot.
• D. Resolution of the clot.

Correct answer: B

Rationale: Cerebral hemorrhage is a significant complication associated with thrombolytic therapy in stroke treatment. Thrombolytic therapy aims to dissolve clots, but it increases the risk of bleeding, including cerebral hemorrhage. This risk is especially high when the therapy is administered quickly after a stroke, sometimes before confirming the type of stroke. Air embolism (Choice A) is not a common complication of thrombolytic therapy. Expansion of the clot (Choice C) and resolution of the clot (Choice D) are not expected outcomes of thrombolytic therapy; the therapy is specifically used to dissolve clots, not to expand or resolve them.

2. A 23-year-old patient in the 27th week of pregnancy has been hospitalized on complete bed rest for 6 days. She experiences sudden shortness of breath, accompanied by chest pain. Which of the following conditions is the most likely cause of her symptoms?

• A. Myocardial infarction due to a history of atherosclerosis.
• B. Pulmonary embolism due to deep vein thrombosis (DVT).
• C. Anxiety attacks due to worries about her baby's health.
• D. Congestive heart failure due to fluid overload.

Correct answer: B

Rationale: In a hospitalized patient on prolonged bed rest, the most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can dislodge and travel to the lungs, causing a pulmonary embolism. Myocardial infarction (Choice A) is less likely in a young patient without a significant history of atherosclerosis. Anxiety attacks (Choice C) may present with similar symptoms but are less likely in this context. Congestive heart failure (Choice D) is less probable given the acute onset of symptoms and absence of typical signs like peripheral edema in this case.

3. Research participants are involved in a trial that incidentally separates them into two groups. One group receives an intervention, while the other group does not. Both groups are compared for outcomes. What type of research method is this?

• A. Experimental design
• B. Double-blind experiment
• C. Randomized controlled trial
• D. Repeated measures design

Correct answer: C

Rationale: A randomized controlled trial is a research method in which participants are randomly assigned to either a treatment or control group. This design helps eliminate bias and allows for the comparison of outcomes between the two groups. In this scenario, where participants are separated into intervention and non-intervention groups for comparison, it aligns with the characteristics of a randomized controlled trial. The key feature distinguishing it from the other options is the random assignment of participants to groups, ensuring that both groups are comparable at the start of the study. Double-blind experiments involve blinding both participants and researchers to treatment allocation, which is not explicitly mentioned in the scenario. Experimental design refers to a broader category that includes various types of research designs beyond just randomized controlled trials. Repeated measures design involves collecting multiple observations from the same participants over time, which is not the case described in the scenario.

4. What is a key principle of patient teaching that must take place to ensure patient safety?

• A. Family members should be present
• B. Teaching must be documented
• C. Understanding must be confirmed
• D. Teaching should be provided by multiple staff members

Correct answer: C

Rationale: A key principle of patient teaching that ensures patient safety is the confirmation of understanding. To ensure patient safety, it is crucial to confirm that the patient comprehends the information provided. This confirmation can be achieved by having the patient repeat back the information or demonstrate understanding through return demonstration. Documenting the patient's understanding is essential to track the effectiveness of the teaching session and ensure that the patient is equipped with the necessary knowledge for their safety. Family members being present or having multiple staff members provide teaching may be beneficial in certain situations, but the primary focus should be on confirming the patient's understanding to enhance safety and promote effective learning.

5. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.
