1. Which of the following is a fat-soluble vitamin?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin B-6
- D. Riboflavin
Correct answer: B
Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K. Choice A, Vitamin C, is water-soluble, not fat-soluble. Choice C, Vitamin B-6, and Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.
2. A 2-year-old child has been brought to the clinic for a well-child checkup. What is the best way for the nurse to begin the assessment?
- A. Ask the parent to place the child on the examining table.
- B. Have the parent remove all of the child's clothing before the examination.
- C. Allow the child to keep a security object such as a toy or blanket during the examination.
- D. Initially focus the interactions on the child, essentially ignoring the parent until the child's trust has been obtained.
Correct answer: C
Rationale: The best place to examine the toddler is on the parent's lap. Toddlers understand symbols; therefore, a security object is helpful. Initially, the focus is more on the parent, which allows the child to adjust gradually and to become familiar with you. A 2-year-old child does not like to take off his or her clothes. Therefore, ask the parent to undress one body part at a time.
3. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
4. Where is the duodenum located in the digestive system?
- A. It is the first part of the small intestine, located immediately after the stomach.
- B. It is the section of the digestive system where the gall bladder delivers bile.
- C. It is the section of the small intestine where the pancreas delivers digestive juices.
- D. None of the above.
Correct answer: D
Rationale: The duodenum is the first part of the small intestine, located immediately after the stomach. It is where the majority of digestion takes place in the gut. The pancreas delivers digestive juices containing amylase and lipase, while the gall bladder delivers bile to aid in the digestion of fats. Choice A incorrectly states that the duodenum is the third section of the small intestine, which is inaccurate. Choice B incorrectly associates the duodenum with the gall bladder, which is not where the duodenum is located. Choice C incorrectly states that the duodenum is where the pancreas delivers digestive juices, which is partly correct but not the main function of the duodenum. Therefore, the correct answer is 'None of the above' as none of the choices accurately describe the location or functions of the duodenum.
5. A healthcare professional realizes after a patient has left the office that they forgot to document the patient's complaint of a sore throat. Which of the following choices would BEST correct the error?
- A. Pull out that page of the chart and rewrite it with the correct information.
- B. Put one line through the original Chief Complaint, write 'ERROR,' your initials, and today's date. Make the correction by rewriting the Chief Complaint with the correct information.
- C. Go to the next available line of the SOAP notes. Write the current date, then write 'Late Entry.' Place the date and time when the patient stated they had a sore throat. Sign and date the entry.
- D. All of the above are incorrect.
Correct answer: C
Rationale: When adding information to a patient's chart after the encounter, using the term 'Late Entry' is essential. This clearly indicates that the information was added after the fact and helps to maintain the accuracy and integrity of the medical record. Option A is incorrect because removing a page from the chart and rewriting it can lead to inaccuracies and is not a recommended practice for correcting errors. Option B suggests marking the original Chief Complaint as an error, which may not be clear to future readers of the chart and could lead to confusion. Option D is incorrect as it dismisses the correct approach outlined in Option C, which is the best way to handle the situation of missed documentation during a patient encounter.
