The community health nurse is performing a home visit to an 84-year-old woman recovering from hip surgery. The
nurse notes that the woman seems uncharacteristically confused and has dry mucous membranes. When asked about her
fluid intake, the patient states, I stop drinking water early in the day because it is just too difficult to get up during the
night to go to the bathroom. What would be the nurses best response?
- A. I will need to have your medications adjusted so you will need to be readmitted to the hospital for a complete
workup - B. Limiting your fluids can create imbalances in your body that can result in confusion. Maybe we need to
adjust the timing of your fluids. - C. It is normal to be a little confused following surgery, and it is safe not to urinate at night.
- D. If you build up too much urine in your bladder, it can cause you to get confused, especially when your body is
under stress.
Correct Answer: B
Rationale: The correct answer is B because limiting fluids can lead to dehydration, which can cause confusion and dry mucous membranes. Adjusting the timing of fluids can help maintain hydration without causing frequent nighttime bathroom trips. Choice A is incorrect because hospital readmission is not necessary at this point. Choice C is incorrect as it normalizes confusion post-surgery and dangerous practice of avoiding urination at night. Choice D is incorrect because urine accumulation in the bladder does not directly cause confusion; dehydration is the primary concern.

The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What
should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?
- A. Choose a hairless site if available.
- B. Consider potential effects on the patients mobility when selecting a site.
- C. Have the patient briefly hold his arm over his head before insertion
- D. Leave the tourniquet on for at least 3 minutes.
Correct Answer: B
Rationale: The correct answer is B because considering potential effects on the patient's mobility is crucial when selecting a site for IV insertion. Mobility can be affected if the IV is placed in a joint area or on the dominant hand. This could limit the patient's ability to move freely during and after the procedure. Therefore, it is important to choose a site that will not hinder the patient's movement.
A: Choosing a hairless site is not the most important factor when selecting a site for IV insertion.
C: Having the patient hold his arm over his head before insertion is not necessary and may cause discomfort for the patient.
D: Leaving the tourniquet on for at least 3 minutes is not recommended as it can lead to complications such as venous stasis.
While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?
- A. Grade 3 phlebitis at IV site
- B. infection at IV site
- C. Thrombosed area at IV site
- D. infiltration at IV site
Correct Answer: A
Rationale: The correct answer is A: Grade 3 phlebitis at IV site. This finding indicates inflammation of the vein due to irritants from the IV catheter, supported by red streak and palpable cord. Grade 3 phlebitis involves pain, redness, swelling, and palpable venous cord. Infection (B) typically presents with signs like pus, warmth, and fever. Thrombosis (C) involves a blood clot, not a palpable cord. Infiltration (D) is leakage of IV fluid into surrounding tissues, not related to palpable cord and red streak.
A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?
- A. Administer topical lidocaine to the site.
- B. Place warm compresses on the site.
- C. . Administer prescribed oral pain medication.
- D. Massage the site with scented oils.
Correct Answer: B
Rationale: The correct answer is B: Place warm compresses on the site. Warm compresses can help increase blood flow, reduce pain, and promote healing at the site of inflammation. The warmth can help dilate blood vessels, increasing circulation to the area and promoting the removal of inflammatory substances. This can help alleviate pain and reduce swelling. Administering topical lidocaine (choice A) may not address the underlying cause of pain and redness. Administering oral pain medication (choice C) may be necessary for severe pain but may not directly address the local inflammation. Massaging the site with scented oils (choice D) can potentially introduce more irritants and should be avoided in cases of inflammation.
A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 22 mEq/L. Which client condition should the nurse correlate with these results?
- A. Diarrhea and vomiting for 36 hours
- B. . Anxiety-induced hyperventilation
- C. Chronic obstructive pulmonary disease (COPD)
- D. Diabetic ketoacidosis and emphysema
Correct Answer: B
Rationale: The correct answer is B: Anxiety-induced hyperventilation. The arterial blood gas values show a pH of 7.48 (alkalosis) with low PaCO2 (respiratory alkalosis), which is consistent with hyperventilation due to anxiety. HCO3 is within normal range, ruling out metabolic causes. A: Diarrhea and vomiting would lead to metabolic acidosis with low pH and decreased HCO3. C: COPD would typically present with respiratory acidosis (high PaCO2) and normal to high HCO3. D: Diabetic ketoacidosis and emphysema would show metabolic acidosis with low pH and low HCO3.
Diagnostic testing has been ordered to differentiate between normal anion gap acidosis and high anion gap acidosis
in an acutely ill patient. What health problem typically precedes normal anion gap acidosis?
- A. Metastases
- B. Excessive potassium intake
- C. Water intoxication
- D. Excessive administration of chloride
Correct Answer: D
Rationale: The correct answer is D: Excessive administration of chloride. Normal anion gap acidosis is commonly caused by an excessive intake of chloride-containing solutions like normal saline during treatment. This leads to an increase in the plasma chloride concentration, causing a decrease in the anion gap. Metastases (A) are not typically associated with normal anion gap acidosis. Excessive potassium intake (B) would not lead to normal anion gap acidosis but rather hyperkalemia. Water intoxication (C) can lead to dilutional hyponatremia but not normal anion gap acidosis.
