1. What does preload refer to?

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

2. Madge is a 91-year-old nursing home resident with a history of dementia and atrial fibrillation who has been admitted to the hospital for treatment of pneumonia. As you are performing her bed bath, you note bruising around her breasts and genital area. What potential issue should be of major concern in Madge's situation?

Correct answer: C

Rationale: Bruising around the breasts and genitals should trigger concern for sexual abuse. Elder abuse is a growing problem in America, and nurses are uniquely positioned to recognize and intervene on behalf of vulnerable populations, such as the elderly. According to the National Center on Elder Abuse (NCEA), major types of elder abuse include physical abuse, sexual abuse, emotional or psychological abuse, neglect, abandonment, financial or material exploitation, and self-neglect. In this scenario, given Madge's age, history of dementia, and the presence of unexplained bruising in sensitive areas, sexual abuse must be considered as a major concern. Idiopathic thrombocytopenic purpura (ITP) is a platelet disorder that presents with excessive bruising and bleeding, but it is less likely in this case as the bruising pattern is suggestive of a different cause. Embolic stroke is a neurological condition that typically presents with sudden onset neurological deficits and is not related to the observed bruising. Nursing home-acquired pneumonia (NHAP) is a common issue in elderly residents but would not manifest as bruising in specific areas like the breasts and genitals.

3. A triage nurse has four clients arrive in the emergency department within 15 minutes. Which client should the triage nurse send back to be seen first?

Correct answer: B

Rationale: The correct answer is the teenager who suffered singed facial hair while camping. This client is in the greatest danger with a potential risk of respiratory distress. Singed facial hair indicates exposure to heat or fire in close range, which could have caused serious damage to the interior of the lungs. It's crucial to prioritize this client as the interior lining of the lungs has no nerve fibers, so swelling may not be immediately noticeable. The other choices, while concerning, do not present an immediate life-threatening situation. The infant's condition may be serious but does not pose an immediate danger of respiratory distress. The elderly client's symptoms could indicate gastrointestinal issues, which are important but not as urgent as potential respiratory compromise. The middle-aged client's pain behind the right scapula, while uncomfortable, does not indicate an acute life-threatening condition requiring immediate attention.

4. Which of the following medical terms means 'surgical fixation of the stomach'?

Correct answer: C

Rationale: The correct answer is 'Gastropexy,' which means 'surgical fixation of the stomach.' This procedure involves surgically fixing the stomach in place. 'Abdominorrhaphy' refers to suturing or repairing the abdomen, not related to fixing the stomach. 'Gastroplasty' is a surgical reconstruction of the abdomen, not specifically related to fixing the stomach. 'Abdominorrhexis' refers to the rupture or tearing of the abdomen, not a surgical fixation procedure.

5. Which of these statements is true regarding the use of Standard Precautions in the healthcare setting?

Correct answer: C

Rationale: Standard Precautions are designed to reduce the risk for transmission of microorganisms from both recognized and unrecognized sources. They are intended for use with all patients, regardless of their risk or presumed infection status. Standard Precautions apply to all body fluids, secretions, and excretions except sweat - whether or not they contain visible blood, non-intact skin, or mucous membranes. Hands should be washed with soap and water if visibly soiled with blood or body fluids. Alcohol-based hand rubs can be used if hands are not visibly soiled. Choice A is incorrect because Standard Precautions apply to all body fluids, secretions, and excretions except sweat. Choice B is incorrect because alcohol-based hand rub should be used when hands are not visibly dirty. Choice D is incorrect because Standard Precautions are not limited to situations involving non-intact skin, excretions with visible blood, or expected mucous membrane contact.
