The body system that functions to maintain fluid balance, support immunity, and contains the spleen is the:
- A. Lymphatic System
- B. Digestive System
- C. Urinary System
- D. Respiratory System
Correct Answer: A
Rationale: The Lymphatic System is responsible for maintaining fluid balance and supporting immunity. It contains organs like the spleen, tonsils, thymus, lymph nodes, and lymph vessels. The spleen, a part of the lymphatic system, plays a crucial role in filtering blood and storing blood cells. The Digestive System is primarily involved in the breakdown and absorption of nutrients, not fluid balance or immunity. The Urinary System is responsible for filtering waste products from the blood and regulating fluid balance, but it does not support immunity or contain the spleen. The Respiratory System is focused on gas exchange and oxygenating the blood, not fluid balance or immunity.

Which body plane divides the body into right and left sides?
- A. Frontal Plane
- B. Medial Plane
- C. Median Plane
- D. Transverse Plane
Correct Answer: C
Rationale: The correct answer is the Median Plane, also known as the sagittal plane. It divides the body into right and left sides. The Frontal Plane, or coronal plane, divides the body into front and back sections. The Transverse Plane divides the body into superior (upper) and inferior (lower) sections. Therefore, choices A, B, and D are incorrect as they do not specifically divide the body into right and left sides.
The nurse is developing a plan of care for an infant after surgical intervention for imperforate anus. The nurse should include in the plan that which position is the most appropriate one for the infant in the postoperative period?
- A. Prone position
- B. Supine with no head elevation
- C. Side-lying with the legs extended
- D. Supine with the head elevated 45 degrees
Correct Answer: A
Rationale: The most appropriate position for an infant after surgical intervention for imperforate anus is the prone position. Placing the infant in a prone position helps keep the hips elevated, reducing edema and pressure on the surgical site. This position promotes optimal healing and comfort for the infant. Option B, supine with no head elevation, does not provide the necessary elevation to reduce pressure on the surgical site. Option C, side-lying with the legs extended, does not offer the same benefits as the prone position in terms of reducing pressure on the surgical site. Option D, supine with the head elevated 45 degrees, does not specifically address the need for hip elevation to prevent pressure on the surgical site. Therefore, the correct choice is the prone position for this postoperative care scenario.
A registered nurse who usually works in a spinal rehabilitation unit is floated to the emergency department. Which of these clients should the charge nurse assign to this RN?
- A. A middle-aged client who says, "I took too many diet pills"? and "my heart feels like it is racing out of my chest."?
- B. A young adult who says, "I hear songs from heaven. I need money for beer. I quit drinking two (2) days ago for my family. Why are my arms and legs jerking?"?
- C. An adolescent who has been on pain medications for terminal cancer with an initial assessment finding of pinpoint pupils and a relaxed respiratory rate of 11.
- D. An elderly client who reports having taken a "large crack hit"? 10 minutes prior to walking into the emergency room.
Correct Answer: C
Rationale: When assigning a floated nurse from another unit to a client in the emergency department, the goal is to choose a patient with minimal anticipated immediate complications. In this scenario, the adolescent with terminal cancer who has been on pain medications and presents with pinpoint pupils and a relaxed respiratory rate of 11 is the most stable option. These assessment findings indicate opioid toxicity, which, while serious, has the least risk of immediate complications compared to the other clients. Choice A involves a middle-aged client experiencing symptoms of possible cardiac issues due to diet pill overdose, which requires urgent intervention. Choice B presents a young adult with concerning symptoms of potential psychosis or substance withdrawal, requiring immediate attention. Choice D involves an elderly client who recently used crack, posing a high-risk situation that requires prompt evaluation and intervention. Therefore, the correct choice is the adolescent with opioid toxicity, as this client has the least immediate risk of complications among the options provided.
In a 68-year-old man, a gradual loss of hearing is known as _____________.
- A. presbycusis
- B. xerostomia
- C. myopia
- D. presbyopia
Correct Answer: A
Rationale: The correct answer is 'presbycusis.' Presbycusis is the age-related gradual loss of hearing ability, commonly seen in the elderly population. Xerostomia refers to dry mouth, myopia is nearsightedness, and presbyopia is the age-related loss of the eye's ability to focus on close objects. Given Mr. Roberts' age and symptom of gradual hearing loss, presbycusis is the most likely diagnosis. Xerostomia, myopia, and presbyopia do not match the sensory change described in the question, making them incorrect choices.
What is the flap of tissue that covers the trachea upon swallowing called?
- A. Epidermis
- B. Endocardium
- C. Epiglottis
- D. Epistaxis
Correct Answer: C
Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.
