A nurse is reviewing the medical records of four clients. The nurse should identify which of the following client findings that requires follow-up care.
A client who received a Mantoux test 48 hr ago and has an induration
A client who is taking bumetanide and has a potassium level of 3.6 mEq/L
A client who is scheduled for a colonoscopy and is taking sodium phosphate
A client who is taking warfarin and has an INR of 1.8
The Correct Answer is D
A. Induration after a Mantoux test is a common response and does not necessarily require follow-up care.
B. A potassium level of 3.6 mEq/L is within the normal range (3.5-5.0 mEq/L).
C. Sodium phosphate is commonly used for bowel preparation before procedures like colonoscopy.
D. Correct. An INR of 1.8 for a client on warfarin is below the therapeutic range (usually 2.0- 3.0 for most indications), indicating that the client's blood may not be adequately anticoagulated. This requires follow-up to adjust the warfarin dose.

Explanation
A. "Try using an abdominal support belt." - An abdominal support belt is recommended to provide support to the growing abdomen and can help alleviate backaches that are common during pregnancy.
B. "Take hot showers to help relieve itching." - This statement is incorrect. Hot showers can actually worsen itching and dry out the skin. Lukewarm showers are recommended instead.
C. "Wear loose-fitting clothing." - This statement is correct. Loose-fitting clothing can provide comfort and reduce irritation, especially in areas experiencing itching.
D. "Wear flat or low-heeled shoes." - This statement is correct. Flat or low-heeled shoes provide better support and stability during pregnancy, reducing the risk of falls.
E. "You can douche twice weekly." - This statement is incorrect. Douching is not recommended during pregnancy as it can disrupt the natural balance of vaginal flora and increase the risk of infections.
F. "Eat two large meals a day." - This statement is incorrect. Eating large meals can lead to discomfort and heartburn. It is better to eat frequent smaller meals throughout the day during pregnancy.
G. "You should avoid fried foods." - This statement is correct. Fried foods can exacerbate heartburn and should be avoided to reduce discomfort.
Correct Answer is D
Explanation
A. Incorrect. Premature atrial complexes do not typically affect the P-R interval. They are characterized by an early P-wave followed by a QRS complex.
B. Incorrect. Complete heart block is characterized by a dissociation between the P-waves and QRS complexes, resulting in no relationship between atrial and ventricular activity.
C. Incorrect. Atrial fibrillation is characterized by chaotic and irregular atrial activity without distinct P-waves, making the P-R interval irrelevant.
D. Correct. In first-degree atrioventricular block, the P-R interval is prolonged beyond the normal range of 0.12-0.20 seconds. A constant P-R interval of 0.35 seconds indicates a first- degree atrioventricular block.
