During surgery, it is found that a client with adenocarcinoma of the rectum has positive peritoneal lymph nodes. What is the next most likely site of metastasis?
- A. brain
- B. bone
- C. liver
- D. mediastinum
Correct Answer: C
Rationale: In cases of adenocarcinoma of the rectum with positive peritoneal lymph nodes, the most likely site of metastasis is the liver. Colon tumors commonly spread through the lymphatics and portal vein to the liver. While metastasis to the brain, bone, or mediastinum is possible, the liver is typically the first to be affected due to the anatomical pathways involved in colorectal cancer metastasis. Therefore, the correct answer is the liver. Metastasis to the brain, bone, or mediastinum would be less likely at this stage of colorectal cancer progression.

A client with a pleural drainage system to suction has gentle bubbling of the water seal. What should the nurse do?
- A. Notify the physician.
- B. Clamp the chest tube.
- C. Replace the system.
- D. Document the finding
Correct Answer: D
Rationale: Gentle bubbling is a normal finding for a client with a pleural drainage system to suction, so it simply needs to be documented for monitoring purposes. If the bubbling becomes vigorous, it could indicate a leak, which would then require further investigation by the nurse. Therefore, the correct action at this point is to document the finding. Notifying the physician is not necessary for gentle bubbling as it is expected. Clamping the chest tube or replacing the system is inappropriate and could potentially harm the client as there is no indication for such actions based on the scenario provided.
A nurse provides instructions to a mother about crib safety for her infant. Which statement by the mother indicates a need for further instructions?
- A. ''Wood surfaces on the crib need to be free of splinters and cracks.''
- B. ''I need to keep large toys out of the crib.''
- C. ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.''
- D. ''The drop side needs to be impossible for my infant to release.''
Correct Answer: C
Rationale: The correct answer is, ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.'' This statement indicates a need for further instructions as the distance between the slats should be no more than 2⅜ inches to prevent entrapment of the infant's head and body, not 4 inches. Allowing a larger gap can pose a risk of entrapment or injury to the infant. Keeping large toys out of the crib is essential to prevent the infant from using them to climb out, which could result in serious injuries. Ensuring the drop side of the crib is impossible for the infant to release is crucial to prevent falls and injuries. Additionally, maintaining wood surfaces on the crib free of splinters, cracks, and lead-based paint is vital for the infant's safety and well-being.
A client states, 'I can leave the diaphragm in place as long as I want after intercourse.' Which statement indicates to the nurse that the client needs further information on how to use the diaphragm?
- A. 'I need to reapply spermicidal cream with repeated intercourse.'
- B. 'The diaphragm needs to be filled with spermicidal cream before insertion.'
- C. 'I can leave the diaphragm in place as long as I want after intercourse.'
- D. 'The diaphragm can be inserted as long as 6 hours before intercourse.'
Correct Answer: C
Rationale: The correct answer is the statement, 'I can leave the diaphragm in place as long as I want after intercourse.' This statement indicates a lack of understanding about the correct use of the diaphragm. The diaphragm must be left in place for at least 6 hours after intercourse to ensure effectiveness and reduce the risk of pregnancy. Leaving the diaphragm in place for an extended period can lead to toxic shock syndrome. Choice A is correct as spermicidal cream needs to be reapplied before each act of intercourse for optimal contraceptive efficacy. Choice B is a correct statement as the diaphragm should be filled with spermicidal cream before insertion to increase its effectiveness. Choice D is also accurate as the diaphragm can be inserted up to 6 hours before intercourse to allow time for proper placement and effectiveness.
What instruction should a client who is about to undergo pelvic ultrasonography be given by a healthcare provider?
- A. "Urinate prior to the test."?
- B. "Have someone drive you home."?
- C. "Do not drink after midnight."?
- D. "Drink plenty of water."?
Correct Answer: D
Rationale: The correct instruction for a client about to undergo pelvic ultrasonography is to 'Drink plenty of water.' A full bladder is required to serve as a landmark to define pelvic organs during the procedure. It is important to ensure the bladder is adequately filled. 'Urinate prior to the test' (Choice A) would not be appropriate as a full bladder is needed for better visualization. 'Have someone drive you home' (Choice B) is unnecessary as no sedation is given during the procedure, so the client can drive home on their own. 'Do not drink after midnight' (Choice C) is unrelated and not necessary for a pelvic ultrasonography examination.
A test that can correctly identify those who do not have a given disease is:
- A. specific.
- B. sensitive.
- C. negative culture
- D. marginal finding.
Correct Answer: A
Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.
