A young adult client, admitted to the emergency department following a motor vehicle collision, is transfused with 4 units of PRBCs. The client's pretransfusion hematocrit is 17%. Which hematocrit value should the nurse expect the client to have after all PRBCs have been transfused?
- A. 23%
- B. 25%
- C. 27%
- D. 29%
Correct Answer: D
Rationale: One unit of PRBCs typically raises the hematocrit by 3%. Since the client received 4 units, the hematocrit is expected to increase by approximately 12% (4 units x 3% per unit). Therefore, the nurse should expect the client's hematocrit to be 29% after all PRBCs have been transfused. Choices A, B, and C are incorrect as they do not account for the cumulative effect of multiple PRBC units on the hematocrit level.

Which additional congenital malformation is expected in 80% of infants with a myelomeningocele?
- A. Cerebral palsy
- B. Hydrocephalus
- C. Meningitis
- D. Neuroblastoma
Correct Answer: B
Rationale: Hydrocephalus is the additional congenital malformation expected in 80% of infants with a myelomeningocele. Myelomeningocele is commonly associated with hydrocephalus due to the abnormal accumulation of cerebrospinal fluid in the brain. Cerebral palsy (Choice A) is a motor disorder but not typically associated with myelomeningocele. Meningitis (Choice C) is an infection of the meninges and is not a congenital malformation. Neuroblastoma (Choice D) is a type of cancer that originates in immature nerve cells and is not a typical association with myelomeningocele.
Which individual has the highest risk for developing skin cancer?
- A. A 16-year-old dark-skinned female who tans in tanning beds once a week.
- B. A 65-year-old fair-skinned male who is a construction worker
- C. A 25-year-old dark-skinned male whose mother had skin cancer.
- D. A 70-year-old fair-skinned female who works as a secretary.
Correct Answer: B
Rationale: The correct answer is B, a 65-year-old fair-skinned male who is a construction worker. Fair-skinned individuals are at higher risk of developing skin cancer due to prolonged sun exposure. Construction workers are often exposed to the sun for long periods, further increasing the risk. Choices A, C, and D are less likely to develop skin cancer compared to choice B due to factors such as age, frequency of tanning bed use, and occupation.
A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
- A. Metabolic acidosis.
- B. Respiratory acidosis.
- C. Metabolic alkalosis.
- D. Respiratory alkalosis.
Correct Answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
During the admission interview, an older client answers some questions inappropriately. The nurse notes that a hearing aid is in one ear. Which intervention is most helpful in assisting the client to hear the nurse's question?
- A. Move to the client's other side.
- B. Speak louder into the client's ear with the hearing aid.
- C. Ask the client to adjust the hearing aid volume.
- D. Restate questions articulating consonants carefully.
Correct Answer: D
Rationale: Restating questions with clear articulation is the most helpful intervention in assisting the client to hear the nurse's question. This approach ensures that the client can better understand the question, especially if there are issues with the hearing aid. Moving to the client's other side or speaking louder into the ear with the hearing aid may not effectively address the problem of clarity in communication. Asking the client to adjust the hearing aid volume assumes that the issue lies solely with the volume, while restating questions with clear articulation can help overcome various hearing difficulties.
Which dietary modification is most appropriate for a client with nephrotic syndrome?
- A. High protein, low sodium
- B. Low protein, high sodium
- C. High protein, high potassium
- D. Low protein, low sodium
Correct Answer: D
Rationale: The most appropriate dietary modification for a client with nephrotic syndrome is a low protein, low sodium diet. This diet helps reduce the workload on the kidneys and manage edema, which are common issues in nephrotic syndrome. Choice A, high protein, low sodium, is not recommended because excessive protein intake can further strain the kidneys. Choice B, low protein, high sodium, is inappropriate as high sodium can worsen fluid retention and hypertension. Choice C, high protein, high potassium, is not ideal as high potassium levels can be problematic for individuals with kidney issues.
