Nokea
The nurse manages care for several clients receiving hormone replacement therapy (HRT). What will the priority assessment by the nurse include as related to side effects?
- A. Pain in the calf
- B. Decreased libido
- C. Low-back pain
- D. Chronic fatigue
Correct Answer: A
Rationale: HRT increases clotting risk, making calf pain a priority due to potential DVT, a life-threatening side effect. Libido , back pain , and fatigue are less urgent. A ensures safety, aligning with HRT risks, making it the priority.

The pregnant patient tells the nurse that her prescribed medication is not as effective as it was before her pregnancy. What is the best response by the nurse?
- A. This is because your blood volume has increased
- B. Tell me how you have been taking your medication
- C. This is because your baby is receiving part of the medication
- D. Maybe the medication has expired; check the label
Correct Answer: A
Rationale: Pregnancy increases blood volume (50% more), diluting drugs, reducing efficacy-e.g., lower concentration per unit volume, a pharmacokinetic shift. Asking about administration checks adherence, not cause. Baby receiving drug is unlikely-placental transfer varies. Expiration is a guess, not tied to pregnancy. Blood volume explains the change, addressing her concern.
The specificity of the adrenergic blocking agents allows the clinician to select a drug to do what?
- A. Have the desired effect
- B. Multiply undesired effects
- C. Increase specificity with higher serum blood levels
- D. Improving concentration in the body
Correct Answer: A
Rationale: This specificity allows the clinician to select a drug that will have the desired therapeutic effects without the undesired effects that occur when the entire sympathetic nervous system is blocked. In general, however, the specificity of adrenergic blocking agents depends on the concentration of drug in the body. Most specificity is lost with higher serum drug levels. The nurse should understand the importance of drug specificity to ensure safe and effective administration.
The nurse administers IV push hydralazine (Apresoline) to a client with severe hypertension. Which assessment finding requires immediate action?
- A. Blood pressure of 140/90 mmHg
- B. Heart rate of 110 beats per minute
- C. Headache
- D. Flushing
Correct Answer: B
Rationale: Hydralazine, a vasodilator, lowers blood pressure but triggers reflex tachycardia. A heart rate of 110 bpm indicates significant compensation, risking ischemia or strain, requiring immediate action (e.g., slowing infusion, notifying physician). BP of 140/90 is improved, not critical. Headache and flushing are expected from vasodilation, less urgent. Tachycardia's potential to destabilize circulation, especially in severe hypertension, aligns with hydralazine's pharmacology'arteriolar relaxation prompts sympathetic response. This finding demands swift intervention to prevent cardiovascular collapse, making B the priority over manageable side effects.
A patient has been taking digoxin at home but took an accidental overdose and has developed toxicity. The patient has been admitted to the telemetry unit, where the physician has ordered
- A. . The patient asks the nurse why the medication is ordere
- B. What is the nurse™s best response?
- C. It will increase your heart rat
- D.
Correct Answer: B
Rationale: The correct response is to inform the patient that the medication, likely an antiarrhythmic agent such as digoxin immune fab (Digibind), helps to convert the irregular heart rhythm caused by digoxin toxicity to a more normal rhythm. This explanation provides a clear understanding of why the medication is being administered in cases of digoxin toxicity. It is important for the nurse to educate the patient about the purpose of the medication and how it will help manage the symptoms of digoxin toxicity.
What is a side effect of Heparin?
- A. nausea
- B. diarrhea
- C. bleeding
- D. bronchospasms
Correct Answer: C
Rationale: A common side effect of Heparin, which is an anticoagulant medication, is the risk of bleeding. Heparin works by preventing the formation of blood clots, which can lead to a bleeding risk as it inhibits the normal clotting process. Patients taking Heparin should be monitored closely for signs of bleeding, such as easy bruising, prolonged bleeding from minor cuts, or blood in the urine or stools. It is important for healthcare providers to closely monitor patients on Heparin therapy and adjust the dosage as needed to minimize the risk of excessive bleeding.
