Your suspected myocardial infarction patient has exhibited ST elevation in Leads II, III, aVF on the electrocardiogram. What area of the heart do you suspect is being damaged?
- A. Lateral wall
- B. Inferior wall
- C. Anterior wall
- D. Septal wall
Correct Answer: B
Rationale: The correct answer is B: Inferior wall. ST elevation in Leads II, III, aVF indicates an inferior wall myocardial infarction, commonly caused by occlusion of the right coronary artery. Lead II views the inferior part of the heart, and Leads III/aVF view the inferior and posterior parts. This pattern suggests damage to the inferior wall supplied by the right coronary artery. Other choices are incorrect as ST elevation in these leads does not correspond to lateral (A), anterior (C), or septal (D) wall infarctions.

Fluids are encouraged for residents who have had a total knee replacement to help prevent
- A. Myocardial infarctions
- B. Urinary tract infections
- C. Depression
- D. Side effects of medication
Correct Answer: B
Rationale: The correct answer is B: Urinary tract infections. Adequate fluid intake post total knee replacement helps prevent UTIs by flushing out bacteria from the urinary tract. Myocardial infarctions are not directly related to fluid intake. Depression is not prevented by fluid intake. Side effects of medication are not specifically prevented by encouraging fluids.
The heart is an example of a(n) ______.
- A. Cell
- B. Tissue
- C. Organ
- D. Body system
Correct Answer: C
Rationale: The correct answer is C: Organ. An organ is a structure made up of different tissues working together to perform a specific function, such as the heart pumping blood. It is not a single cell (A), a group of cells (B), or a collection of organs working together (D). The heart fits the definition of an organ, making choice C the most appropriate.
How may friends and families provide support to residents?
- A. Families and friends provide a link to the outside world.
- B. Families and friends provide much-deserved gifts to staff members.
- C. Families and friends provide physical therapy.
- D. Families and friends restrict mail and correspondence.
Correct Answer: A
Rationale: The correct answer is A because families and friends provide a link to the outside world for residents, helping them stay connected and maintain social relationships. This support is crucial for residents' emotional well-being. Choice B is incorrect as it focuses on staff members, not residents. Choice C is incorrect as physical therapy is typically provided by healthcare professionals, not friends and families. Choice D is incorrect as it suggests a negative impact on residents' communication, which is not supportive.
Which of the following will be missed by DPL?
- A. "Subcapsular hematoma of the spleen"
- B. Liver laceration
- C. Bowel injury
- D. Pancreatic injury
Correct Answer: A
Rationale: The correct answer is A: "Subcapsular hematoma of the spleen" because DPL (Diagnostic Peritoneal Lavage) is a diagnostic procedure used to assess for intra-abdominal injuries, particularly to organs like the liver, bowel, and pancreas. A subcapsular hematoma of the spleen is an injury specific to the spleen, which is not directly evaluated by DPL. The other choices (B: Liver laceration, C: Bowel injury, D: Pancreatic injury) are all potential injuries that can be detected by DPL due to their location within the abdominal cavity and the presence of free intra-abdominal fluid.
The amount that Medicare and Medicaid will pay long-term care facilities for services is based on
- A. The resident's background
- B. The resident's need upon admission and throughout his stay
- C. The size of the facility
- D. The financial contributions from the resident's family
Correct Answer: B
Rationale: The correct answer is B because Medicare and Medicaid reimburse long-term care facilities based on the resident's need for services upon admission and throughout their stay. This is determined through assessments of the resident's health condition, functional status, and care requirements. The reimbursement is directly tied to the level of care provided to ensure that residents receive appropriate services.
Choice A (The resident's background) is incorrect because reimbursement is not based on the resident's personal history but on their current health and care needs. Choice C (The size of the facility) is incorrect as reimbursement is not determined by the facility's size but by the individual resident's care requirements. Choice D (The financial contributions from the resident's family) is incorrect as Medicare and Medicaid payments are not influenced by the resident's family contributions but are solely based on the resident's care needs.
