Nclex Exam Cram Practice Questions
1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?
- A. blood urea nitrogen
- B. serum calcium
- C. serum ammonia
- D. serum creatinine
Correct answer: C
Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.
2. Which situation is an example of the use of evidence-based practice in the delivery of client care?
- A. Encouraging a client who has had a stroke to consume thickened liquids and soft foods
- B. Picking up a dislodged radiation implant with long-handled forceps and placing it in a lead container to minimize radiation exposure
- C. Pouring 1 to 2 mL of sterile solution that will be used for wound cleansing into a plastic-lined waste receptacle before pouring the solution into a sterile basin
- D. Blowing on a fingerstick site to dry it after cleaning the site with an alcohol swab
Correct answer: C
Rationale: Evidence-based practice is an approach that integrates client preferences, clinical expertise, and the best research evidence to deliver quality care. Pouring sterile solution into a plastic-lined waste receptacle before using it for wound cleansing reflects evidence-based practice by preventing the entrance of harmful bacteria into the wound. Option A is incorrect because encouraging a stroke client to consume thickened liquids and soft foods is appropriate, not thin liquids and foods that pose a choking risk. Option B is incorrect as picking up a radiation implant with long-handled forceps to minimize radiation exposure is a safety measure, not evidence-based practice. Option D is incorrect because blowing on a fingerstick site after cleaning can recontaminate the site, which goes against best practices in infection control.
3. A nurse is preparing to administer medications to a client via a nasogastric (NG) tube. Before administering the medication, the nurse must first take which action?
- A. Check the client's apical pulse
- B. Check when the last feeding was given
- C. Check the placement of the tube
- D. Check when the last medications were given
Correct answer: C
Rationale: Before administering medications through an NG tube, the nurse must first check the placement of the tube to prevent aspiration. This is done by aspirating gastric contents and measuring the pH. Checking the client's apical pulse is unrelated to NG tube medication administration. Checking when the last feeding was given is important but not a priority before administering medications. Checking when the last medications were given is also not directly related to ensuring the safe administration of medications through an NG tube. Ensuring the correct placement of the tube is crucial to prevent complications such as pulmonary aspiration.
4. The nurse is preparing to administer IV Vancomycin to a client. Which of the following nursing actions should be taken first?
- A. Performing a physical assessment prior to administration
- B. Obtaining the most recent lab values regarding renal function
- C. Reviewing peaks and troughs for the past few days
- D. Ensuring the client is not allergic to the medication
Correct answer: D
Rationale: Before administering any medication, including IV Vancomycin, it is crucial to ensure that the client is not allergic to the medication. This is the most critical action to prevent any potential allergic reactions. While performing a physical assessment is important, it may not be as time-sensitive as checking for allergies. Obtaining lab values related to renal function is also significant with Vancomycin due to its potential nephrotoxicity, but ensuring the client's safety by checking for allergies takes precedence. Reviewing peaks and troughs is important for monitoring drug levels, but it is a secondary step compared to checking for allergies prior to administration.
5. A client with dumping syndrome should ___________ while a client with GERD should ___________.
- A. lie down 1 hour after meals; sit up at least 30 minutes after meals
- B. sit up 1 hour after meals; lie flat 30 minutes after meals
- C. sit up after meals; sit up after meals
- D. lie down after meals; lie down after meals
Correct answer: A
Rationale: Clients with dumping syndrome should lie down after eating to decrease the symptoms of dumping syndrome, which include rapid gastric emptying leading to various gastrointestinal symptoms. On the other hand, clients with GERD should sit up at least 30 minutes after meals to prevent the backflow of stomach acid into the esophagus. This position helps reduce symptoms by allowing gravity to keep the stomach contents in place, minimizing the chances of reflux. Therefore, the correct answer is to lie down 1 hour after eating for dumping syndrome and to sit up at least 30 minutes after eating for GERD. Choices B, C, and D are incorrect because they do not accurately reflect the appropriate positioning for each condition.
