A nurse is caring for a client prescribed enoxaparin for deep vein thrombosis prophylaxis. Which of the following client assessments requires immediate intervention?

A. Platelet count of 95,000/mm³

B. Blood pressure of 145/90 mmHg

C. Heart rate of 95 beats per minute

D. Pain at the injection site

Correct Answer: A
Rationale: A platelet count of 95,000/mm³ requires immediate intervention as it is low and increases the risk of bleeding, which is a potential complication of enoxaparin therapy. Low platelet counts can predispose the patient to hemorrhage, and administering anticoagulants like enoxaparin in such cases can further increase the bleeding risk. Monitoring platelet counts is crucial during anticoagulant therapy to prevent serious bleeding complications. The other options do not pose immediate risks related to enoxaparin therapy. A slightly elevated blood pressure, a heart rate of 95 beats per minute, and pain at the injection site are common findings that may not warrant immediate intervention in this context.

A nurse is caring for a client who is prescribed warfarin. Which of the following laboratory tests should the nurse review to evaluate the therapeutic effect of this medication?

• A. aPTT
• B. INR
• C. Serum glucose
• D. Bilirubin

Correct Answer: B
Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is the most reliable test for evaluating the therapeutic effects of warfarin therapy. INR measures the clotting ability of the blood and helps determine if the dosage of warfarin is within the therapeutic range. Choice A, aPTT, is not typically used to monitor the effects of warfarin. Choice C, Serum glucose, and choice D, Bilirubin, are not relevant to monitoring the therapeutic effect of warfarin.

A client is prescribed propranolol. Which of the following client history findings would require the nurse to clarify this medication prescription?

• A. Asthma
• B. Hypertension
• C. Tachydysrhythmias
• D. Urolithiasis

Correct Answer: A
Rationale: The correct answer is A: Asthma. Clients with asthma should avoid Beta2 Blockade agents like propranolol as they can lead to bronchoconstriction, potentially worsening asthma symptoms. Choice B, hypertension, is not a contraindication for propranolol; in fact, it is commonly prescribed for hypertension. Choice C, tachydysrhythmias, is often an indication for propranolol due to its antiarrhythmic properties. Choice D, urolithiasis, does not directly impact the use of propranolol.

A nurse is preparing to administer an intramuscular injection to an adult client. At what angle should the nurse administer the medication using the ventrogluteal site?

• A. a 45-degree angle
• B. a 60-degree angle
• C. a 75-degree angle
• D. a 90-degree angle

Correct Answer: D
Rationale: Intramuscular injections in the ventrogluteal site should be administered at a 90-degree angle. This angle ensures that the medication reaches the muscle tissue effectively. Angles less than 90 degrees can cause subcutaneous injection instead of intramuscular, leading to slower absorption of the medication. Angles greater than 90 degrees risk hitting bone or nerves, causing unnecessary pain or injury. Therefore, the correct angle for administering intramuscular injections in the ventrogluteal site is 90 degrees.

A client is prescribed digoxin 0.125 mg daily for heart failure. Which of the following client reports should concern the nurse as a sign of digoxin toxicity?

• A. Increased appetite
• B. Visual disturbances
• C. Weight gain
• D. Constipation

Correct Answer: B
Rationale: Visual disturbances such as blurred vision or seeing halos around lights are common signs of digoxin toxicity. Increased appetite, weight gain, and constipation are not typically associated with digoxin toxicity. Weight gain could be a sign of worsening heart failure rather than digoxin toxicity. Increased appetite and constipation are not specific signs of digoxin toxicity and are less likely to be related.
