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

Answer and Explanation

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.

Correct Answer is C

Explanation

A. Incorrect. Leaving a nasogastric tube clamped after administering oral medication is a mistake, but it may not necessarily be considered malpractice if it doesn't result in harm or negligence.
B. Incorrect. Placing a yellow bracelet on a client at risk for falls is a safety measure, and it's not an example of malpractice.
C. Correct. Administering potassium via IV bolus can be dangerous and is considered malpractice if not done properly. Rapid administration of potassium via IV bolus can lead to serious cardiac complications.
D. Incorrect. Documenting communication with a provider in the progress notes of the client's medical record is a standard practice and not an example of malpractice.

A. Premature atrial complexes B. Complete heart block C. Atrial fibrillation D. First-degree atrioventricular block

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.
