A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?

The correct answer is choiced. A client who is taking warfarin and has an INR of 1.8.

Choice A rationale:

An induration after a Mantoux test indicates a positive reaction, but it does not necessarily require immediate follow-up unless the induration is significant and the client has risk factors for tuberculosis.

Choice B rationale:

Sodium phosphate is commonly used as a bowel preparation for colonoscopy. This does not typically require follow-up unless the client experiences adverse effects such as dehydration or electrolyte imbalance.

Choice C rationale:

A potassium level of 3.6 mEq/L is within the normal range (3.5-5.0 mEq/L). Therefore, this finding does not require follow-up.

Choice D rationale:

An INR of 1.8 for a client taking warfarin is below the therapeutic range for most indications (typically 2.0-3.0). This requires follow-up to adjust the warfarin dosage to achieve the desired anticoagulation effect.

The correct answer is choice A: “We can review some information to help you select a safe alternative practitioner.” This statement shows respect for the client’s interest in alternative therapies and offers guidance on how to choose a reliable and qualified provider. Alternative therapies can provide some benefits for people with rheumatoid arthritis, such as reducing pain, inflammation, and stiffness, but they should be used as a complement to conventional treatments and not as a substitute.

Choice B is wrong because it implies that the client has no role in deciding their own treatment plan and that alternative therapies are not worth considering.

This may discourage the client from sharing their preferences and concerns with the provider.

Choice C is wrong because it suggests that online support groups are a reliable source of information about alternative remedies, which may not be true.

Online sources may contain inaccurate, misleading, or harmful information that could jeopardize the client’s health and safety.

Choice D is wrong because it encourages the client to try any therapy that fits their personal belief system, without considering the evidence, effectiveness, or potential risks of such therapies. Some alternative therapies may interact with medications, cause side effects, or worsen the condition.

Normal ranges for rheumatoid arthritis are not applicable in this question, as it is not asking about laboratory values or disease activity measures. However, some common tests used to diagnose and monitor rheumatoid arthritis include erythrocyte sedimentation rate (ESR), Creactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, and joint ultrasound or X-ray.

The normal ranges for these tests may vary depending on the laboratory and the method used.
