1. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?
- A. triglyceride level
- B. liver function tests
- C. a glucose tolerance test
- D. a complete blood count
Correct answer: B
Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.
2. A client asks a nurse working in a dental office what type of drug the dentist uses to provide anesthesia during the extraction of the client's wisdom teeth. The dentist uses an anesthetic gas, also known as laughing gas. This agent is:
- A. nitrous oxide.
- B. nitrogen.
- C. nitric oxide.
- D. nitrogen dioxide.
Correct answer: A
Rationale: The correct answer is nitrous oxide. Nitrous oxide is commonly known as laughing gas and is used as an anesthetic gas for procedures like dental extractions. It produces analgesia and mild euphoria without loss of consciousness. Nitrogen is a nonmetallic element found in air, while nitric oxide is a vasodilator produced from L-arginine. Nitrogen dioxide is a poisonous gas found in smog and exhaust fumes and is not used for anesthesia.
3. The nurse is caring for a client complaining of intense headaches with increasing pain for the past one month. An MRI is ordered. In reviewing the client's information, which piece of information is of concern?
- A. Allergy to shellfish
- B. Has a cardiac pacemaker
- C. A diabetic
- D. No IV access
Correct answer: B
Rationale: The correct answer is 'Has a cardiac pacemaker.' If a client with a cardiac pacemaker undergoes an MRI, the magnetic field can interfere with the pacemaker's function, leading to serious complications or even death. It is crucial to ensure that the pacemaker is compatible with MRI imaging or to consider alternative imaging modalities. The other choices, such as 'Allergy to shellfish,' 'A diabetic,' and 'No IV access,' are not direct contraindications for an MRI scan and do not pose the same level of risk as having a cardiac pacemaker.
4. Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?
- A. mycobacterium tuberculosis
- B. clostridium tetani
- C. staphylococcus aureus
- D. human immunodeficiency virus
Correct answer: C
Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.
5. A woman is in the active phase of labor. An external monitor has been applied, and a fetal heart deceleration of uniform shape is observed, beginning just as the contraction is underway and returning to the baseline at the end of the contraction. Which of the following nursing actions is most appropriate?
- A. Administer O2 if necessary.
- B. Turn the client on her left side.
- C. Notify the physician.
- D. No action is necessary.
Correct answer: D
Rationale: The correct answer is 'No action is necessary.' In this scenario, the fetal heart deceleration of uniform shape observed is an early deceleration resulting from head compression. Early decelerations are benign and typically do not require any intervention as they mirror the contraction pattern. It is essential to closely observe both the mother and the baby. Administering O2 (Choice A) is not necessary as early decelerations do not indicate fetal distress. Turning the client on her left side (Choice B) is not required for early decelerations. Notifying the physician (Choice C) is not needed for this type of deceleration, as it is a normal response to head compression during labor.
