Which of the following intravenous solutions is hypotonic?
- A. Normal saline
- B. Ringer's lactate
- C. 0.45% saline
- D. 5% dextrose in normal saline  A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET F
Correct Answer: C
Rationale: A hypotonic solution has a lower concentration of solutes compared to the cells in the body. 0.45% saline is hypotonic because it has a lower concentration of sodium chloride compared to the normal extracellular fluid in the body. When this solution is administered intravenously, water will move into the cells to balance the concentration gradient, potentially causing cellular swelling. A hypotonic solution is used to rehydrate cells in cases of hypernatremia or dehydration with cellular dehydration.

Which action by the nurse demonstrates use of evidence-based practice (EBP)?
- A. Gathering equipment for a procedure
- B. Documenting changes in a patient's status
- C. Questioning the use of daily central line dressing changes
- D. Clarifying a physician's prescription for morphine
Correct Answer: C
Rationale: Questioning the use of daily central line dressing changes demonstrates the use of evidence-based practice (EBP) by the nurse. In EBP, decisions about patient care should be informed by the best available evidence, clinical expertise, and patient preferences. By questioning the necessity of daily dressing changes for central lines, the nurse is seeking to ensure that the care provided is based on sound evidence and best practices rather than simply following routine procedures. This critical thinking and questioning approach aligns with the principles of evidence-based practice.
A client is undergoing a diagnostic work-up for suspected testicular cancer. When obtaining the client's history, the nurse checks for known risk factors for this type of cancer. Testicular cancer has been linked to:
- A. Testosterone therapy during childhood
- B. Early onset of puberty
- C. Sexually transmitted disease
- D. Cryptorchidism
Correct Answer: D
Rationale: Cryptorchidism, also known as undescended testicle, is a known risk factor for testicular cancer. Men who had cryptorchidism, a condition where one or both testicles fail to descend into the scrotum before birth, have a higher risk of developing testicular cancer compared to those without this condition. The abnormal positioning of the testicle outside the scrotum may disrupt normal testicular development and increase the likelihood of malignant transformation. Therefore, clients with a history of cryptorchidism are at increased risk for testicular cancer and warrant close monitoring and follow-up.
A blood sample for measurement of bilirubin is required from a newborn receiving phototherapy. In what environment should this blood sample be drawn?
- A. While phototherapy lights are turned off
- B. While newborn remains under phototherapy lights
- C. When newborn is covered with a blanket
- D. When newborn has been off phototherapy for 30 to 60 minutes
Correct Answer: D
Rationale: The blood sample for measurement of bilirubin should be drawn when the newborn has been off phototherapy for 30 to 60 minutes. The reason for this is that phototherapy can alter bilirubin levels through photoisomerization, making it challenging to interpret the results accurately while the newborn is still under the lights. Allowing a period of 30 to 60 minutes for the newborn to be off phototherapy helps to ensure that the bilirubin level obtained from the blood sample reflects a more accurate baseline level. This practice helps in guiding clinical management decisions related to managing hyperbilirubinemia in newborns.

What equipment should the nurse prepare for the primary care provider when a woman says she is concerned about possible Chlamydia infection?
- A. Chlamydia slide
- B. Chlamydia collection kit
- C. Chlamydia swab
- D. Chlamydia wet mount
Correct Answer: B
Rationale: When a woman expresses concerns about a possible Chlamydia infection, the nurse should prepare a Chlamydia collection kit for the primary care provider. This kit typically includes everything needed to collect a specimen for testing, such as a swab for the patient to provide a genital sample. This sample can then be sent to a laboratory for testing to confirm the presence of Chlamydia. Having the appropriate collection kit ready ensures that the primary care provider can promptly gather the necessary information to make an accurate diagnosis and provide appropriate treatment if needed.
