An adult has a Hickman type central venous catheter and needs to have blood drawn from it. Which of the following should the nurse do first?
- A. Use sterile technique to assemble supplies needed
- B. Aspirate and discard the first 10 ml of the blood
- C. First flush the catheter with heparinized solution, then withdraw the blood
- D. Remove the cap of the catheter and replace it with a new one
Correct Answer: C
Rationale: The correct answer is C because flushing the central venous catheter with a heparinized solution before blood withdrawal is essential to maintain catheter patency and prevent clot formation. This step ensures the catheter is clear of any blockages, allowing for accurate blood sampling. Choice A is incorrect because assembling supplies should come after preparing the catheter. Choice B is incorrect as discarding blood before flushing the catheter may lead to inaccurate test results. Choice D is incorrect as replacing the catheter cap without flushing may lead to clot formation and catheter malfunction.

Which of the ff. would the nurse explain to the patient is indicated by a Snellen chart finding 20/80?
- A. The eye can see at 80 feet what the normal eye can see at 20 feet.
- B. The eye can see at 20 feet what the normal eye can see at 80 feet.
- C. The eye can see four times what the normal eye can see.
- D. The eye sees normally.
Correct Answer: B
Rationale: The correct answer is B because a Snellen chart reading of 20/80 means the patient can see at 20 feet what a normal eye can see at 80 feet. This indicates that the patient's vision is below average. Choice A is incorrect because it reverses the numerator and denominator. Choice C is incorrect because it does not accurately represent the Snellen chart findings. Choice D is incorrect because 20/80 is not considered normal vision.
A client in the terminal stage of cancer is receiving continuous infusion of morphine (Duramorph) for pain management. Which assessment finding suggests that the client is experiencing an adverse effect of this drug?
- A. Voiding of 350mL of concentrated urine in
- B. Irregular heart rate of 82 beats/min
- C. Pupils constricted and equal
- D. Respiratory rate of 8breaths/min
Correct Answer: D
Rationale: The correct answer is D because a respiratory rate of 8 breaths/min indicates respiratory depression, a serious adverse effect of morphine. Morphine is a central nervous system depressant that can suppress the respiratory drive, leading to hypoventilation and potentially respiratory failure. This is a life-threatening complication that requires immediate intervention.
A: Voiding of 350mL of concentrated urine is not typically associated with morphine use.
B: An irregular heart rate of 82 beats/min is within a normal range and not a common adverse effect of morphine.
C: Pupils constricted and equal is a common side effect of morphine due to its action on the central nervous system, not necessarily indicating an adverse effect.
Which of the following is not a criterion for a valid informed consent that a nurse should identify?
- A. freely given
- B. with coercion
- C. has an explanation of procedures
- D. describes the alternatives
Correct Answer: B
Rationale: The correct answer is B: with coercion. Informed consent must be freely given without any form of coercion to ensure the individual's autonomy and decision-making capacity. Coercion can lead to involuntary consent, undermining the principle of respect for autonomy. Choices A, C, and D are all criteria for valid informed consent. Choice A ensures the individual is voluntarily agreeing without any external pressure. Choice C ensures the individual understands the procedures involved, promoting transparency. Choice D ensures the individual is aware of alternative options, allowing for an informed decision-making process.
When documenting subjective data, the nurse should do which of the following?
- A. Use the client’s own words placed in quotation marks.
- B. Paraphrase the information stated by the client.
- C. Validate the information with the client’s family prior to documentation.
- D. Record the information using nonspecific words.
Correct Answer: A
Rationale: The correct answer is A because using the client's own words in quotation marks ensures accurate representation of their subjective data. It maintains the integrity of the information provided by the client and improves communication between healthcare providers. Paraphrasing (choice B) may lead to misinterpretation or distortion of the client's statements. Validating with the client's family (choice C) may introduce bias or inaccurate information. Recording with nonspecific words (choice D) decreases the clarity and specificity of the documentation, which is essential for effective communication and decision-making in healthcare.
In order to educate clients, the nurse should understand that the most common site of cancer for a female is the:
- A. Uterine cervix
- B. Vagina
- C. Uterine body
- D. Fallopian tube
Correct Answer: C
Rationale: The correct answer is C: Uterine body. The rationale is that the most common site of cancer for females is uterine body, specifically endometrial cancer. This is due to the high prevalence of hormonal imbalances and estrogen exposure, which are risk factors for this type of cancer. The other choices, A: Uterine cervix, B: Vagina, and D: Fallopian tube, are less common sites of cancer in females compared to the uterine body. Understanding the prevalence and risk factors associated with each site of cancer is crucial for nurses to educate clients effectively.
