A nurse is caring for a client who has been prescribed a DASH diet.
Which of the following is the best protein source for the nurse to instruct the client to eat?
Pork.
Turkey.
Beef.
Lamb.
The Correct Answer is B
Choice A rationale
Pork, particularly cuts like bacon or sausage, often contains high levels of saturated fat and sodium, which are detrimental to cardiovascular health and contradict the principles of the DASH diet. The DASH diet emphasizes lean protein sources to reduce fat intake and promote heart health.
Choice B rationale
Turkey, especially lean cuts like turkey breast without skin, is an excellent protein source for a DASH diet. It is low in saturated fat and cholesterol, providing high-quality protein necessary for tissue repair and maintenance without contributing to elevated blood pressure or dyslipidemia.
Choice C rationale
Beef, particularly fattier cuts, can be high in saturated fat and cholesterol, which should be limited in a DASH diet designed to lower blood pressure and improve cardiovascular health. While lean beef can be consumed in moderation, other protein sources are often preferred for their lower fat content.
Choice D rationale
Lamb, especially some cuts, can be high in saturated fat and cholesterol, similar to fattier cuts of beef. While it offers protein, its higher saturated fat content makes it a less optimal choice compared to leaner options for individuals adhering to a DASH diet focused on reducing cardiovascular risk factors.

Correct Answer is D
Explanation
Choice A rationale
A ventricular pacemaker is designed to pace the ventricles, not the atria. Therefore, a pacemaker spike appearing before each P wave would indicate atrial pacing, which is not the primary function of a ventricular pacemaker. P waves represent atrial depolarization, and a ventricular pacemaker's stimulus is delivered to the ventricles to initiate a QRS complex.
Choice B rationale
A pacemaker spike appearing after each QRS complex suggests either oversensing, undersensing with competitive rhythms, or a malfunction. The purpose of a pacemaker spike is to *initiate* depolarization, not to follow it. If the spike occurs after the QRS, it indicates that the ventricle has already depolarized, and the spike is not contributing to ventricular contraction.
Choice C rationale
A pacemaker spike appearing with each T wave would be inappropriate and potentially dangerous. The T wave represents ventricular repolarization, a vulnerable period during which an electrical stimulus can induce life-threatening arrhythmias like ventricular fibrillation (R-on-T phenomenon). Pacing should occur before ventricular depolarization, not during repolarization.
Choice D rationale
A ventricular pacemaker functions by delivering an electrical impulse to the ventricle when its intrinsic rate falls below a programmed threshold. This impulse, seen as a pacemaker spike on the ECG, should precede ventricular depolarization, thus initiating a QRS complex. This indicates that the pacemaker is effectively stimulating ventricular contraction at the appropriate time.
Correct Answer is B
Explanation
Choice A rationale
While depression can co-occur with various headache types, it is not consistently identified as a direct or primary precipitating factor common to both tension-type and cluster headaches; rather, stress is a more widely recognized shared trigger.
Choice B rationale
Stress is a well-established precipitating factor for both tension-type headaches, where muscle tension is often exacerbated by stress, and cluster headaches, where stress can trigger attacks in susceptible individuals, demonstrating a shared neurobiological pathway.
Choice C rationale
Smoking is a strong precipitating factor specifically for cluster headaches, with a high prevalence among sufferers, but it is not a commonly cited or significant precipitating factor for the typical presentation of tension-type headaches.
Choice D rationale
Poor posture is frequently associated with and can contribute to the development of tension-type headaches due to increased muscle strain in the neck and shoulders, but it is not a recognized or common precipitating factor for cluster headaches.
