1. A nurse checks the residual volume from a client’s nasogastric tube feeding before administering an intermittent tube feeding and finds 35 mL of gastric contents. What should the nurse do before administering the prescribed 100 mL of formula to the client?
- A. Pour the residual volume into the nasogastric tube through a syringe with the plunger removed
- B. Discard the residual volume properly and record it as output on the client’s fluid balance record
- C. Dilute the residual volume with water and inject it into the nasogastric tube, applying pressure on the plunger
- D. Mix the residual volume with the formula and pour it into the nasogastric tube, using a syringe without a plunger
Correct answer: A
Rationale: After checking the residual feeding contents, the nurse should pour the residual volume back into the stomach by removing the syringe bulb or plunger and then pouring the gastric contents, using the syringe, into the nasogastric tube. This helps ensure that the residual volume is reintroduced into the client's gastrointestinal tract. Option B is incorrect because discarding the residual volume without reinstilling it into the stomach can lead to inaccurate medication administration and potential electrolyte imbalances. Option C is incorrect as diluting the residual volume with water and injecting it under pressure can cause aspiration or discomfort for the client. Option D is incorrect because mixing the residual volume with the formula can alter the prescribed dosage and consistency, potentially affecting the client's nutritional intake and causing complications.
2. After checking the client’s gag reflex following an esophagogastroduodenoscopy (EGD), which action should the nurse take?
- A. Taking the client’s vital signs
- B. Giving the client a drink of water
- C. Monitoring the client for a sore throat
- D. Being alert to complaints of heartburn
Correct answer: A
Rationale: After an esophagogastroduodenoscopy (EGD), the nurse's priority is to assess the client's airway by checking the gag reflex. Once this assessment is done, the next step is to take the client's vital signs to monitor for any signs of complications such as bleeding or changes in respiratory status. Giving the client water immediately after the procedure may not be appropriate, as the client may still have a compromised gag reflex and is at risk for aspiration. Monitoring for a sore throat is important but not the immediate priority post-procedure. Being alert to complaints of heartburn is relevant for assessing the client's symptoms but is not the priority immediately after checking the gag reflex.
3. Which information about mammograms is most important to provide a post-menopausal female client?
- A. Breast self-examinations are not necessary if annual mammograms are obtained.
- B. Radiation exposure is minimized by shielding the abdomen with a lead-lined apron.
- C. Yearly mammograms should be done regardless of previous normal screenings.
- D. Women at high risk should have annual routine and ultrasound mammograms.
Correct answer: C
Rationale: The most important information to provide a post-menopausal female client regarding mammograms is that yearly mammograms should be done regardless of previous normal screenings. It is crucial for post-menopausal women to continue regular mammograms as they are at a higher risk for breast cancer. Option A is incorrect as breast self-examinations are still recommended in addition to mammograms. Option B is not the most important information compared to the importance of regular mammograms. Option D is not the most important advice for all post-menopausal females but specifically for those at high risk, indicating a more targeted approach.
4. A client has a chest drainage system in place. The fluid in the water seal chamber rises and falls during inspiration and expiration. The nurse interprets this finding as an indication that:
- A. The tube is patent
- B. There is probably a kink in the tubing
- C. Suction should be added to the system
- D. The client is retaining airway secretions
Correct answer: A
Rationale: The correct answer is A: 'The tube is patent.' When the fluid in the water seal chamber rises and falls during inspiration and expiration, it indicates that the chest tube is patent, allowing for proper drainage. Choice B is incorrect because a kink in the tubing would obstruct the flow of fluid, leading to abnormal fluctuations in the water seal chamber. Choice C is incorrect as adding suction to the system is not indicated based on the described finding. Choice D is incorrect as the rising and falling of fluid in the water seal chamber is not indicative of the client retaining airway secretions.
5. A young adult client, admitted to the Emergency Department following a motor vehicle collision, is transfused with 4 units of PRBCs (packed red blood cells). The client's pretransfusion hematocrit is 17%. Which hematocrit value should the nurse expect the client to have after all the PRBCs have been transfused?
- A. 0.19
- B. 0.09
- C. 0.39
- D. 0.29
Correct answer: D
Rationale: The expected increase in hematocrit after transfusion is approximately 3% per unit of PRBCs. Since the client received 4 units, the expected increase would be 4 x 3% = 12%. Therefore, adding this to the pretransfusion hematocrit of 17% would result in an expected post-transfusion hematocrit of 29%. Choice A (0.19) is incorrect as it doesn't consider the incremental increase per unit of PRBCs. Choices B (0.09) and C (0.39) are also incorrect as they do not align with the expected increase in hematocrit following the transfusion of 4 units of PRBCs.
