1. Which of the following statements should the nurse use to best describe a very low-calorie diet (VLCD) to a client?
- A. "This diet can be used when there is close medical supervision."?
- B. "This is a long-term treatment measure that assists obese people who can't lose weight."?
- C. "The VLCD consists of solid food items that are pureed to facilitate digestion and absorption."?
- D. "A VLCD contains very little protein."?
Correct answer: A
Rationale: The correct answer is, "This diet can be used when there is close medical supervision."? Very low-calorie diets (VLCDs) are used in the clinical treatment of obesity under close medical supervision. The diet is low in calories, high in quality protein, and has a minimum of carbohydrates to spare protein and prevent ketosis. Choice B is incorrect because VLCDs are typically short-term interventions. Choice C is incorrect because VLCDs usually consist of nutritionally complete liquid formulations, not solid food items that are pureed. Choice D is incorrect because VLCDs actually contain a high quality of protein, although the overall caloric content is very low.
2. A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:
- A. urinary excess
- B. hyperpituitarism
- C. urinary deficit
- D. hyperthyroidism
Correct answer: C
Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output. Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.
3. Erythropoietin used to treat anemia in clients with renal failure should be given in conjunction with:
- A. iron, folic acid, and B12.
- B. an increase in protein in the diet.
- C. vitamins A and C.
- D. an increase in calcium in the diet.
Correct answer: A
Rationale: Erythropoietin is necessary for red blood cell (RBC) production, and in clients with renal failure who lack endogenous erythropoietin, exogenous erythropoietin is administered. However, for erythropoietin to effectively stimulate RBC production, adequate levels of iron, folic acid, and vitamin B12 are crucial. These nutrients are essential for RBC synthesis and maturation. Therefore, the correct answer is to give iron, folic acid, and B12 with erythropoietin. Choice B, an increase in protein in the diet, is not necessary for RBC production and may exacerbate uremia in clients with renal failure. Choices C and D, vitamins A and C, and an increase in calcium in the diet, respectively, are not directly related to RBC production and are not required to enhance the effectiveness of erythropoietin.
4. The nurse is caring for a client receiving warfarin therapy (Coumadin®) following a stroke. The client's PT/INR was completed at 7:00 A.M. prior to the morning meal with an INR reading of 4.0. Which of the following is the nurse's first priority?
- A. Call the physician to request an increase in the Coumadin® dose.
- B. Administer a vitamin K injection IM and notify the physician of the results.
- C. Assess the client for bleeding around the gums or in the stool and notify the physician of the lab results and latest dose of Coumadin®.
- D. Notify the next shift to hold the daily dose of Coumadin® scheduled for 5:00 P.M.
Correct answer: B
Rationale: In a client receiving warfarin therapy with a high INR of 4.0, the nurse's first priority is to administer a vitamin K injection intramuscularly (IM) and notify the physician of the results. An INR of 4.0 indicates excessive anticoagulation, putting the client at risk of bleeding. Vitamin K is the antidote for warfarin overdose and helps to reverse its effects. It is crucial to administer vitamin K promptly to prevent bleeding complications. Calling the physician to request an increase in the Coumadin® dose is inappropriate and dangerous in this situation, as it would further raise the INR. Assessing the client for bleeding and notifying the physician is important but not the first priority when faced with a critically high INR. Holding the daily dose of Coumadin® may be necessary after administering vitamin K, but it is not the primary action needed to address the acute high INR level.
5. When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, what should be instructed?
- A. switch to a stronger dose of the same medication.
- B. discontinue the medication for a few weeks.
- C. continue taking the same medication, but use it more frequently.
- D. use a combination of medications for better relief.
Correct answer: B
Rationale: When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, it is crucial to discontinue the medication for a few weeks. Prolonged use of decongestant drops can lead to rebound congestion, which is relieved by stopping the medication for a period of time. Nasal congestion occurs due to various factors like infection, inflammation, or allergy, leading to swelling of the nasal cavity. Nasal decongestants work by stimulating alpha-adrenergic receptors, causing vasoconstriction and shrinking of nasal mucous membranes. However, prolonged use can result in vasodilation, worsening nasal congestion. Switching to a stronger dose of the same medication is not recommended as it can exacerbate the issue. Continuing the same medication more frequently or using a combination of medications are also not advised and may lead to side effects. Educating individuals on proper decongestant use and potential risks of prolonged usage is essential, especially for those with specific health conditions.
