When caring for a client with a possible diagnosis of placenta previa, which of the following admission procedures should the nurse omit?
- A. perineal shave
- B. enema
- C. urine specimen collection
- D. blood specimen collection
Correct Answer: B
Rationale: The correct answer is 'enema.' Administering an enema to a client with placenta previa can dislodge the placenta, leading to an increased risk of bleeding and complications. It is crucial to avoid any interventions that may disrupt the placenta's positioning. Collecting urine and blood specimens are necessary for diagnostic purposes and monitoring, while a perineal shave is a routine procedure that does not pose a risk to the client with placenta previa.
What happens if folic acid is administered to treat anemia without determining its underlying cause?
- A. Erythropoiesis is inhibited
- B. Excessive levels of folic acid might accumulate, causing toxicity
- C. The symptoms of pernicious anemia might be masked, delaying treatment
- D. Intrinsic factor is destroyed
Correct Answer: C
Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.
A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?
- A. The patient may be developing CHF
- B. The patient may be having a MI
- C. The patient may be developing COPD
- D. The patient may be having an onset of PVD
Correct Answer: B
Rationale: In this scenario, the patient's symptoms of shortness of breath (SOB) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness. Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or peripheral vascular disease (PVD).
A client had a colostomy done one day ago. Which of the following is an abnormal finding when assessing the stoma?
- A. mild edema
- B. minimal bleeding
- C. rose color
- D. dark red color
Correct Answer: D
Rationale: A dark red color is an abnormal finding when assessing the stoma as it indicates inadequate blood supply, possibly due to ischemia. Mild edema, minimal bleeding, and a rose color are expected findings one day post colostomy surgery. Mild edema can be present due to tissue trauma and inflammation, minimal bleeding can occur initially, and a healthy stoma typically appears pink to red, known as a rose color, indicating good blood supply and tissue perfusion. Therefore, the dark red color is the abnormal finding in this scenario.
A nurse is instructing a patient on the order of sensations with the application of an ice water bath for a swollen right ankle. Which of the following is the correct order of sensations experienced with an ice water bath?
- A. cold, burning, aching, and numbness
- B. burning, aching, cold, and numbness
- C. aching, cold, burning, and numbness
- D. cold, aching, burning, and numbness
Correct Answer: A
Rationale: The correct order of sensations experienced with an ice water bath is cold, burning, aching, and numbness, as stated by the acronym CBAN (cold, burn, ache, numbness). Option A is the correct sequence. Choice B is incorrect as it starts with burning, which typically follows the cold sensation. Choice C is incorrect as aching is usually felt after the burning sensation. Choice D is incorrect as aching usually occurs after the burning sensation.
